The LTA27 44-V precision operational amplifier combines the low offset and drift of the LTA77/OP77/OP07 with both high speed and low noise. The LTA27 offers outstanding dc precision and acperformance, including 25 μV ultralow offset, 0.2 μV/°C maximum drift over temperature, 0.32 μV P-Pinput voltage noise, 4.5 MHz gain bandwidth product and 3 V/μs slew rate. External offset nulling is not required in the majority of circuits.A CMRR of 114 dB minimum and PSRR of 10 μV/V (100 dB) maximum virtually eliminate errorscaused by common-mode signals and power supply drifts. This combination of outstanding characteristics makes the LTA27 ideally suited for high resolution instrumentation and other tight error budget systems.The robust design of the LTA27 provides ease-of-use to the circuit designer: integrated RF/EMI rejection filter, no phase reversal in overdrive conditions, and high electro-static discharge (ESD) protection. The LTA27 is optimized for operation at voltages from +8 V (±4 V) to +44 V (±22 V) over the extended temperature range of −40 °C to +125 °C.

The LT1002 dual, matched precision operational amplifiers combine excellent individual amplifier performance with tight matching and temperature tracking between amplifiers. In the design, processing, and testing of the device, particular attention has been paid to the optimization of the entire distribution of several key parameters and their matching. Consequently, the specifications of even the low cost commercial grade (LT1002C) have been spectacularly improved compared to presently available devices. Essentially, the input offset voltage of all units is less than 80µV, and matching between amplifiers is consistently beter than 60µV (see distribution plot below). Input bias and offset currents, channel separation, common mode and power suply rejections of the LT1002C are all specified at levels which were previsouly attainable only on very expensive, selected grades of other dual devices. Power dissipation is nearly halved compared to the most popular precision duals, without adversely affecting noise or speed performance. A by-product of lower dissipation is decreased warm-up drift. For even better performance in a single precision op amp, refer to the LT1001 data sheet. A bridge signal conditioning application is shown below. This circuit illustrates the requirement for both excellent matching and individual amplifier specifications.
