outputopampswitha30MHzgain-bandwidthproductand

a 10V/µs slew rate.

■

Gain-Bandwidth Product: 30MHz

Low Supply Current per Amplifier: 3.5mA

Input Common Mode Range Includes Both Rails

Output Swings Rail-to-Rail

Input Offset Voltage, Rail-to-Rail: 525µV Max

Input Offset Current: 150nA Max

Input Bias Current: 1000nA Max

Open-Loop Gain: 1000V/mV Min

Low Input Noise Voltage: 6nV/√Hz Typ

Low Distortion: –91dBc at 100kHz

Wide Supply Range: 2.7V to ±15V

Large Output Drive Current: 35mA Min

Dual in 8-Pin PDIP and SO Packages

Quad in Narrow 14-Pin SO Package

The LT1630/LT1631 have excellent DC precision over the

full range of operation. Input offset voltage is typically less

than 150µV and the minimum open-loop gain of one

million into a 10k load virtually eliminates all gain error. To

maximize common mode rejection, the LT1630/LT1631

employ a patented trim technique for both input stages,

one at the negative supply and the other at the positive

supply, that gives a typical CMRR of 106dB over the full

input range.

The LT1630/LT1631 maintain their performance for sup-

pliesfrom2.7Vto36Vandarespecifiedat3V,5Vand±15V

supplies. The inputs can be driven beyond the supplies

without damage or phase reversal of the output. The

output delivers load currents in excess of 35mA.

APPLICATIONS

■

Active Filters

The LT1630 is available in 8-pin PDIP and SO packages

withthestandarddualopamppinout.TheLT1631features

the standard quad op amp configuration and is available in

a 14-pin plastic SO package. These devices can be used as

plug-in replacements for many standard op amps to

improve input/output range and performance.

APPLICATIONS INFORMATION

Rail-to-Rail Input and Output

transistor Q5 will steer the tail current I₁to the current

mirror Q6/Q7, activating the NPN differential pair and the

PNP pair becomes inactive for the rest of the input com-

mon mode range up to the positive supply.

The LT1630/LT1631 are fully functional for an input and

output signal range from the negative supply to the posi-

tive supply. Figure 1 shows a simplified schematic of the

amplifier. The input stage consists of two differential

amplifiers, a PNP stage Q1/Q2 and an NPN stage Q3/Q4

that are active over different ranges of input common

mode voltage. The PNP differential input pair is active for

input common mode voltages V_CMbetween the negative

supply to approximately 1.4V below the positive supply.

As V_CMmoves closer toward the positive supply, the

The output is configured with a pair of complementary

common emitter stages Q14/Q15 that enables the output

to swing from rail to rail. These devices are fabricated on

Linear Technology’s proprietary complementary bipolar

process to ensure similar DC and AC characteristics.

Capacitors C1 and C2 form local feedback loops that lower

the output impedance at high frequencies.

Figure 1. LT1630 Simplified Schematic Diagram

Power Dissipation

To ensure that the LT1630/LT1631 are used properly,

calculate the worst-case power dissipation, get the ther-

mal resistance for a chosen package and its maximum

junction temperature to derive the maximum ambient

temperature.

The LT1630/LT1631 amplifiers combine high speed and

large output current drive in a small package. Because the

amplifiers operate over a very wide supply range, it is

possible to exceed the maximum junction temperature of

150°C in plastic packages under certain conditions. Junc-

tion temperature T_Jis calculated from the ambient tem-

perature T_Aand power dissipation P_Das follows:

Example: An LT1630CS8 operating on ±15V supplies and

driving a 500Ω, the worst-case power dissipation per

APPLICATIONS INFORMATION

Input Offset Voltage

The LT1630/LT1631’s input stages are protected against

large differential input voltages by a pair of back-to-back

diodes D5/D6. When a differential voltage of more than

0.7V is applied to the inputs, these diodes will turn on,

preventing the emitter-base breakdown of the input

transistors. The current in D5/D6 should be limited to

less than 10mA. Internal 225Ω resistors R6 and R7 will

limittheinputcurrentfordifferentialinputsignalsof4.5V

or less. For larger input levels, a resistor in series with

either or both inputs should be used to limit the current.

Worst-casedifferentialinputvoltageusuallyoccurswhen

the output is shorted to ground. In addition, the amplifier

is protected against ESD strikes up to 3kV on all pins.

The offset voltage changes depending upon which input

stage is active, and the maximum offset voltages are

trimmed to less than 525µV. To maintain the precision

characteristics of the amplifier, the change of V_OSover the

entire input common mode range (CMRR) is guaranteed

to be less than 525µV on a single 5V supply.

Input Bias Current

The input bias current polarity depends on the input

common mode voltage. When the PNP differential pair is

active, the input bias currents flow out of the input pins.

They flow in the opposite direction when the NPN input

stage is active. The offset voltage error due to input bias

currents can be minimized by equalizing the noninverting

and inverting input source impedance.

Capacitive Load

The LT1630/LT1631 are wideband amplifiers that can

drive capacitive loads up to 200pF on ±15V supplies in a

unity-gain configuration. On a 3V supply, the capacitive

load should be kept to less than 100pF. When there is a

need to drive larger capacitive loads, a resistor of 20Ω to

50Ω should be connected between the output and the

capacitiveload.Thefeedbackshouldstillbetakenfromthe

output so that the resistor isolates the capacitive load to

ensure stability.

Output

The outputs of the LT1630/LT1631 can deliver large load

currents; the short-circuit current limit is 70mA. Take care

to keep the junction temperature of the IC below the

absolute maximum rating of 150°C (refer to the Power

Dissipation section). The output of these amplifiers have

reverse-biased diodes to each supply. If the output is

forced beyond either supply, unlimited current will flow

throughthesediodes.Ifthecurrentistransientandlimited

to several hundred mA, no damage to the part will occur.

Feedback Components

The low input bias currents of the LT1630/LT1631 make it

possible to use the high value feedback resistors to set the

gain. However, care must be taken to ensure that the pole

formedbythefeedbackresistorsandthetotalcapacitance

at the inverting input does not degrade stability. For

instance, the LT1630/LT1631 in a noninverting gain of 2,

set with two 20k resistors, will probably oscillate with

10pF total input capacitance (5pF input capacitance and

5pF board capacitance). The amplifier has a 5MHz cross-

ing frequency and a 52° phase margin at 6dB of gain. The

feedback resistors and the total input capacitance form a

pole at 1.6MHz that induces a phase shift of 72° at 5MHz!

The solution is simple: either lower the value of the

resistors or add a feedback capacitor of 10pF or more.

Overdrive Protection

To prevent the output from reversing polarity when the

input voltage exceeds the power supplies, two pairs of

crossing diodes D1 to D4 are employed. When the input

voltage exceeds either power supply by approximately

700mV, D1/D2 or D3/D4 will turn on, forcing the output to

the proper polarity. For this phase reversal protection to

work properly, the input current must be limited to less

than 5mA. If the amplifier is to be severely overdriven, an

external resistor should be used to limit the overdrive

current.

TYPICAL APPLICATIONS

Single Supply, 40dB Gain, 350kHz

Instrumentation Amplifier

Tunable Q Notch Filter

A single supply, tunable Q notch filter as shown in Figure

4 is built with LT1630 to maximize the output swing. The

filter has a gain of 2, and the notch frequency (f_O) is set by

thevaluesofRandC. TheresistorsR10andR11setupthe

DC level at the output. The Q factor can be adjusted by

varying the value of R8. The higher value of R8 will

decrease Q as depicted in Figure 5, because the output

induces less of feedback to amplifier A2. The value of R7

should be equal or greater than R9 to prevent oscillation.

If R8 is a short and R9 is larger than R7, then the positive

feedbackfromtheoutputwillcreatephaseinversionatthe

output of amplifier A2, which will lead to oscillation.

An instrumentation amplifier with a rail-to-rail output

swing,operatingfroma3Vsupplycanbeconstructedwith

the LT1630 as shown in Figure 2. The amplifier has a

nominal gain of 100, which can be adjusted with resistor

R5. The DC output level is set by the difference of the two

inputs multiplied by the gain of 100. Common mode range

can be calculated by the equations shown with Figure 2.

For example, the common mode range is from 0.15V to

2.65V if the output is set at one half of the 3V supply. The

common mode rejection is greater than 110dB at 100Hz

when trimmed with resistor R1. The amplifier has a

bandwidth of 355kHz as shown in Figure 3.

RF Amplifier Control Biasing and DC Restoration

R4

R2

R1

Taking advantage of the rail-to-rail input and output, and

the large output current capability of the LT1630, the

circuit, shown in Figure 6, provides precise bias currents

for the RF amplifiers and restores DC output level. To

ensure optimum performance of an RF amplifier, its bias

point must be accurate and stable over the operating

temperature range. The op amp A1 combined with Q1, Q2,

R1, R2 and R3 establishes two current sources of 21.5mA

to bias RF1 and RF2 amplifiers. The current of Q1 is

determined by the voltage across R2 over R1, which is

replicated in Q2. These current sources are stable and

precise over temperature and have a low dissipated power

due to a low voltage drop between their terminals. The

amplifier A2 is used to restore the DC level at the output.

With a large output current of the LT1630, the output can

be set at 1.5VDC on 5V supply and 50Ω load. This circuit

hasa3dBbandwidthfrom2MHzto2GHzandapowergain

of 25dB.
