100Ω, AV = AV(MAX) = 10, Typical Values Unless
Specified.
differential input, voltage controlled gain stage
followed by a high-speed current feedback Op Amp
which can directly drive a low impedance load. Gain
adjustment range is more than 70dB for up to 10MHz.

Gain Control BW 100MHz
Maximum gain is set by external components and the
gain can be reduced all the way to cut-off. Power
consumption is 370mW with a speed of 135MHz .
Output referred DC offset voltage is less than 350mV
over the entire gain control voltage range. Device-to-
device Gain matching is within 0.7dB at maximum
gain. Furthermore, gain at any VG is tested and the
tolerance is ensured. The output current feedback Op
Amp allows high frequency large signals (Slew Rate
= 1800V/μs) and can also drive heavy load current
(75mA). Differential inputs allow common mode
rejection in low level amplification or in applications
where signals are carried over relatively long wires.
For single ended operation, the unused input can
easily be tied to ground (or to a virtual half-supply in
single supply application). Inverting or non-inverting
gains could be obtained by choosing one input
polarity or the other.
Adjustment Range (Typical Over Temp) 70dB
Gain Matching (Limit) ±0.7dB
Slew Rate 1800V/µs
Supply Current (No Load) 37mA
Linear Output Current ±75mA
Output Voltage (RL = 100Ω) ±3.2V
Input Voltage Noise 6.6nV/√Hz
Input Current Noise 2.4pA/√Hz
THD (20MHz, RL = 100Ω, VO = 2VPP) −57dBc

Variable Attenuator
AGC
To further increase versatility when used in a single
supply application, gain control range is set to be
from −1V to +1V relative to pin 11 potential (ground
pin). In single supply operation, this ground pin is tied
to a "virtual" half supply. Gain control pin has high
input impedance to simplify its drive requirement.
Gain control is linear in V/V throughout the gain
adjustment range. Maximum gain can be set to be
anywhere between 1V/V to 100V/V or higher. For
linear in dB gain control applications, see LMH6502
datasheet.

(1) Electrical Table values apply only for factory testing conditions at the temperature indicated. Factory testing conditions result in very
limited self-heating of the device such that TJ = TA. No ensured specification of parametric performance is indicated in the electrical
tables under conditions of internal self-heating where TJ > TA.
(2) Typical values represent the most likely parametric norm. Bold numbers refer to over temperature limits.
(3) Flat Band Attenuation (Relative To Max Gain) Range Definition: Specified as the attenuation range from maximum which allows gain
flatness specified (either ±0.2dB or ±0.1dB), relative to AVMAX gain. For example, for f<30MHz, here are the Flat Band Attenuation
ranges:±0.2dB:
10V/V down to 1V/V=20dB range±0.1dB:

APPLICATION INFORMATION
THEORY OF OPERATION
The LMH6503 is a linear wideband variable-gain amplifier as illustrated in Figure 59. A voltage input signal may
be applied differentially between the two inputs (+VIN, −VIN), or single-endedly by grounding one of the two
unused inputs. The LMH6503 input buffers convert the input voltage to a current (IRG) that is a function of the
differential input voltage (VINPUT = (+VIN) - (−VIN)) and the value of the gain setting resistor (RG). This current (IRG
)
is then mirrored to a gain stage with a current gain of K (1.72 nominal). The voltage controlled two-quadrant
multiplier attenuates this current which is then converted to a voltage via the output amplifier. This output
amplifier is a current feedback op amp configured as a Transimpedance amplifier. Its Transimpedance gain is the
feedback resistor (RF). The input signal, output, and gain control are all voltages. The output voltage can easily
be calculated as shown in Equation 1:

CHOOSING RF AND RG
RG is calculated using Equation 5. VINPUTMAX is the maximum peak input voltage (Vpk) determined by the
application. IRGMAX is the maximum allowable current through RG and is typically 2.3mA. Once AVMAX is
determined from the minimum input and desired output voltages, RF is then determined using Equation 6. These
values of RF and RG are the minimum possible values that meet the input voltage and maximum gain constraints.
Scaling the resistor values will decrease bandwidth and improve stability.

ADJUSTING OFFSETS
Treating the offsets introduced by the input and output stages of the LMH6503 is accomplished with a two step
process. The offset voltage of the output stage is treated by first applying −1.1V on VG, which effectively isolates
the input stage and multiplier core from the output stage. As illustrated in Figure 61, the trim pot located at R14
on the LMH6503 Evaluation Board (LMH730033) should then be adjusted in order to null the offset voltage seen
at the LMH6503's output (pin 10).

Figure 61. Nulling the Output Offset Voltage
Once this is accomplished, the offset errors introduced by the input stage and multiplier core can then be treated.
The second step requires the absence of an input signal and matched source impedances on the two input pins
in order to cancel the bias current errors. This done, then +1.1V should be applied to VG and the trim pot located
at R10 adjusted in order to null the offset voltage seen at the LMH6503's output. If a more limited gain range is
anticipated, the above adjustments should be made at these operating points. These steps will minimize the
output offset voltage. However, since the offset term itself varies with the gain setting, the correction is not
perfect and some residual output offset will remain.
GAIN ACCURACY
Defined as the ratio of measured gain (V/V), at a certain VG, to the best fit line drawn through the typical gain
(V/V) distribution for −1V < VG < 1V (results expressed in dB) (See Figure 62). The best fit gain (AV) is given by:
AV (V/V) = 4.87VG + 4.61
(7)
(8)
For: −1V ≤ VG ≤ + 1V, RF = 1kΩ, RG = 174Ω
For a VG range, the value specified in the tables represents the worst case accuracy over the entire range. The
"Typical" value would be the worst case ratio between the "Typical Gain" and the best fit line. The "Max" value
would be the worst case between the max/min gain limit and the best fit line.
GAIN MATCHING
Defined as the limit on gain variation at a certain VG (expressed in dB) (See Figure 62). Specified as "Max" only
(no "Typical"). For a VG range, the value specified represents the worst case matching over the entire range. The
"Max" value would be the worst case ratio between the max/min gain limit and the typical gain.

Figure 63 describes the LMH6503's output-referred spot noise density as a function of frequency with AVMAX

10V/V. The plot includes all the noise contributing terms. However, with both inputs terminated in 50Ω, the input
noise contribution is minimal. At AVMAX = 10V/V, the LMH6503 has a typical flat-band input-referred spot noise
density (ein) of 6.6nV/√Hz. For applications with −3dB BW extending well into the flat-band region, the input RMS
voltage noise can be determined from the following single-pole model:

CIRCUIT LAYOUT CONSIDERATIONS
Good high-frequency operation requires all of the de-coupling capacitors shown in Figure 64 to be placed as
close as possible to the power supply pins in order to insure a proper high-frequency low-impedance bypass.
Adequate ground plane and low inductive power returns are also required of the layout. Minimizing the parasitic
capacitances at pins 3, 4, 5, 6, 9, 10 and 12 will assure best high frequency performance. The parasitic
inductance of component leads or traces to pins 4, 5 and 9 should also be kept to a minimum. Parasitic or load
capacitance, CL, on the output (pin 10) degrades phase margin and can lead to frequency response peaking or
circuit oscillation. The LMH6503 is fully stable when driving a 100Ω load. With reduced load (e.g. 1kΩ) there is a
possibility of instability at very high frequencies beyond 400MHz especially with a capacitive load. When the
LMH6503 is connected to a light load as such, it is recommended to add a snubber network to the output (e.g.
100Ω and 39pF in series tied between the LMH6503 output and ground). CL can also be isolated from the output
by placing a small resistor in series with the output (pin 10).
Figure 64. Required Power Supply Decoupling
Component parasitics also influence high frequency results. Therefore it is recommended to use metal film
resistors such as RN55D or leadless components such as surface mount devices. High profile sockets are not
recommended.
Texas Instruments suggests the following evaluation board as a guide for high frequency layout and as an aid in
device testing and characterization:

SINGLE SUPPLY OPERATION
It is possible to operate the LMH6503 with a single supply. To do so, tie pin 11 (GND) to a potential about mid
point between V+ and V−. Two examples are shown in Figure 65 & Figure 66.

OPERATING AT LOWER SUPPLY VOLTAGES
The LMH6503 is rated for operation down to 5V supplies (V+ - V−). There are some specifications shown for
operation at ±2.5V within the data sheet (i.e. Frequency Response, CMRR, PSRR, Gain vs. VG, etc.). Compared
to ±5V operation, at lower supplies:
a)
VG range constricts. Referring to Figure 67, note that VG_MAX (VG voltage required to get maximum gain) is
0.5V (VS = ±2.5V) compared to 1.0V for VS = ±5V. At the same time, gain cut-off (VG_MIN) would shift to
−0.5V from - 1V with VS = ±5V.
Table 1 shows the approximate expressions for various VG voltages as a function of V-:

VG_LIMIT (maximum permissible voltage on VG) is reduced. This is due to limitations within the device
arising from transistor headroom. Beyond this limit, device performance will be affected (non-destructive).
Referring to Figure 67, note that with V+ = 2.5V, and V− = −4V, VG_LIMIT is approaching VG_MAX and already
"Max gain" is reduced by 1dB. This means that operating under these conditions has reduced the
maximum permissible voltage on VG to a level below what is needed to get Max gain. If supply voltages
are asymmetrical, reference Figure 67 and Figure 68 plots to make sure the region of operation is not
overly restricted by the "pinching" of VG_LIMIT, and VG_MAX curves.
"Max_gain" reduces. There is an intrinsic reduction in max gain when the total supply voltage is reduced
(see Figure 43). In addition, there is the more drastic mechanism described in "b" above and shown in
Figure 67.
Similar plots for V+ = 5V operation are shown in Figure 68 for comparison and reference.

FOUR-QUADRANT MULTIPLIER
Applications requiring multiplication, squaring or other non-linear functions can be implemented with four-
quadrant multipliers. The LMH6503 implements a four-quadrant multiplier as illustrated in Figure 69:
Figure 69. Four Quadrant Multiplier
FREQUENCY SHAPING
Frequency shaping and bandwidth extension of the LMH6503 can be accomplished using parallel networks
connected across the RG ports. The network shown in the Figure 70 schematic will effectively extend the
LMH6503's bandwidth.

2nd ORDER TUNABLE BANDPASS FILTER
The LMH6503 Variable-Gain Amplifier placed into a feedback loop provides signal processing function such as in
a 2nd order tunable bandpass filter. The center frequency of the 2nd order bandpass shown in Figure 71 is
adjusted through the use of the LMH6503's gain control voltage, VG. The integrators implemented with two
sections of a LMH6682, provide the coefficients for the transfer function.
