The LT1014D is a quad precision operational amplifier with 14-pin industry-standard configuration. It features lowoffset-voltage temperature coefficient, high gain, low supply current, and low noise.

The LT1014D can be operated with both dual ±15-V and single 5-V power supplies. The common-mode inputvoltage range includes ground, and the output voltage can also swing to within a few milivolts of ground.Crossover distortion is eliminated.

LT1014D-EP


The LT1014D is fully specified for single-supply operation (VCC- = 0). The common-mode input voltage rangeincludes ground, and the output swings within a few millivolts of ground.

Furthermore, the LT1014D has specific circuitry that addresses the difficulties of single-supply operation, both atthe input and at the output. At the input, the driving signal can fall below 0 V, either inadvertently or on atransient basis. If the input is more than a few hundred millivolts below ground, the LT1014D is designed to dealwith the following two problems that can occur:1. On many other operational amplifiers, when the input is more than a diode drop below ground, unlimited

current flows from the substrate (VCC- terminal) to the input, which can destroy the unit. On the LT1014D, the400-Ω resistors in series with the input (see schematic) protect the device even when the input is 5 V belowground.

2. When the input is more than 400 mV below ground (at TA = 25°C), the input stage of similar type operationalamplifiers saturates, and phase reversal occurs at the output. This can cause lockup in servo systems.Because of unique phase-reversal protection circuitry (Q21, Q22, Q27, and Q28), the LT1014D outputs donot reverse, even when the inputs are at -1.5 V (see Figure 25).

However, this phase-reversal protection circuitry does not function when the other operational amplifier on theLT1014D is driven hard into negative saturation at the output. Phase-reversal protection does not work on anamplifier:• When 4's output is in negative saturation (the outputs of 2 and 3 have no effect)• When 3's output is in negative saturation (the outputs of 1 and 4 have no effect)• When 2's output is in negative saturation (the outputs of 1 and 4 have no effect)• When 1's output is in negative saturation (the outputs of 2 and 3 have no effect)

At the output, other single-supply designs either cannot swing to within 600 mV of ground or cannot sink morethan a few microproamperes while swinging to ground. The all-npn output stage of the LT1014D maintains its lowoutput resistance and high gain characteristics until the output is saturated. In dual-supply operations, the outputstage is free of crossover distortion.

LT1014D-EP


The single-supply operation of the LT1014D can be used as a precision comparator with TTL-compatible output.In systems using both operational amplifiers and comparators, the LT1014D can perform multiple duties (seeFigure 26 and Figure 27).

for Various Input Overdrives

The minimum supply voltage for proper operation of the LT1014D is 3.4 V (three Ni-Cad batteries). Typicalsupply current at this voltage is 290 µA; therefore, power dissipation is only 1 mW per amplifier.

Figure 31shows the test circuit for measuring input offset voltage and its temperature coefficient. This circuit withsupply voltages increased to ±20 V is also used as the burn-in configuration.

The peak-to-peak equivalent input noise voltage of the LT1014D is measured using the test circuit shown inFigure 28. The frequency response of the noise tester indicates that the 0.1-Hz corner is defined by only onezero. The test time to measure 0.1-Hz to 10-Hz noise should not exceed 10 seconds, as this time limit acts as anadditional zero to eliminate noise contribution from the frequency band below 0.1 Hz.

An input noise-voltage test is recommended when measuring the noise of a large number of units. A 10-Hz inputnoise-voltage measurement correlates well with a 0.1-Hz peak-to-peak noise reading because both results aredetermined by the white noise and the location of the 1/f corner frequency.

Noise current is measured by the circuit and formula shown in Figure 29. The noise of the source resistors issubtracted.
