OPERATION INSTRUCTION
Features
Description
Single-Supply Operation from +2.5V ~
The
CBM8091/1N(single),
CBM8094(quad) are
+5.5V
CBM8092/2N(dual),
Rail-to-Rail Output
rail-to-rail output voltage feedback amplifiers
offering ease of use and low cost. They have
bandwidth and slew rate typically found in
current feedback amplifiers. All have a wide
input common-mode voltage range and
output voltage swing, making them easy to
use on single supplies as low as 2.5V. Despite
being low cost, the CBM8091 series provide
excellent overall performance. They offer wide
bandwidth to 350MHz (G = +1) along with
0.1dB flatness out to 58MHz (G = +2) and
offer a typical low power of 4.2mA/amplifier.
The CBM8091 series is low distortion and
fast settling make it ideal for buffering high
speed A/D or D/A converters. The
-3dB Bandwidth(G=+1): 350MHz (Typ.)
Low Input Bias Current: 1pA (Typ.)
Quiescent Current: 4.2mA/Amplifier (Typ.)
Operating Temperature: -40°C ~ +125°C
Small Package:
CBM8091 Available in SOT23-5 and SC70-5
Packages
CBM8092 Available in SOP-8 and MSOP-8
Packages
CBM8094 Available in SOP-14 and
TSSOP-14 Packages
CBM8091N Available in SOT23-6 and

APPLICATION NOTES
Size
CBM809X series op amps are unity-gain stable and suitable for a wide range of general-purpose
applications. The small footprints of the CBM809X series packages save space on printed circuit boards and
enable the design of smaller electronic products.
Power Supply Bypassing and Board Layout
CBM809X series operates from a single 2.5V to 5.5V supply or dual ±1.25V to ±2.75V supplies. For best
performance, a 0.1µF ceramic capacitor should be placed close to the VDD pin in single supply operation. For
dual supply operation, both VDD and VSS supplies should be bypassed to ground with separate 0.1µF ceramic
capacitors.
Low Supply Current
The low supply current (typical 4.2mA per channel) of CBM809X series will help to maximize battery life.
They are ideal for battery powered systems.
Operating Voltage
CBM809X series operate under wide input supply voltage (2.5V to 5.5V). In addition, all temperature
specifications apply from -40℃ to +125℃. Most behavior remains unchanged throughout the full operating
voltage range. These guarantees ensure operation throughout the single Li-Ion battery lifetime
Rail-to-Rail Output
Rail-to-Rail output swing provides maximum possible dynamic range at the output. This is particularly
important when operating in low supply voltages. The output voltage of CBM809X series can typically swing to
less than 30mV from supply rail in light resistive loads (>1kΩ), and 120mV of supply rail in moderate resistive
loads (150Ω).
Capacitive Load Tolerance
The CBM809X family is optimized for bandwidth and speed, not for driving capacitive loads. Output
capacitance will create a pole in the amplifier’s feedback path, leading to excessive peaking and potential
oscillation. If dealing with load capacitance is a requirement of the application, the two strategies to consider are
(1) using a small resistor in series with the amplifier’s output and the load capacitance and (2) reducing the
bandwidth of the amplifier’s feedback loop by increasing the overall noise gain. Figure 2. shows a unity gain
follower using the series resistor strategy. The resistor isolates the output from the capacitance and, more
importantly, creates a zero in the feedback path that compensates for the pole created by the output
capacitance.

CBM8091-CBM8092-CBM8094-CBM8091N-CBM8092N
OPERATION INSTRUCTION
The bigger the RISO resistor value, the more stable VOUT will be. However, if there is a resistive
load RL in parallel with the capacitive load, a voltage divider (proportional to RISO/RL) is formed,
this will result in a gain error.
The circuit in Figure 3 is an improvement to the one in Figure 2. RF provides the DC accuracy
by feed-forward the VIN to RL. CF and RISO serve to counteract the loss of phase margin by feeding
the high frequency component of the output signal back to the amplifier’s inverting input,
thereby preserving the phase margin in the overall feedback loop. Capacitive drive can be
increased by increasing the value of CF. This in turn will slow down the pulse response.
Figure 3. Indirectly Driving a Capacitive Load with DC Accuracy
Typical Application Circuits
Differential amplifier
The differential amplifier allows the subtraction of two input voltages or cancellation of a
signal common the two inputs. It is useful as a computational amplifier in making a differential to
single-end conversion or in rejecting a common mode signal. Figure 4. shown the differential
amplifier using CBM809X.

Low Pass Active Filter
The low pass active filter is shown in Figure 5. The DC gain is defined by –R2/R1. The filter has
a -20dB/decade roll-off after its corner frequency ƒC=1/(2πR3C1).
