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.
