Product Overview
The OPA2388 is a Texas Instruments dual zero-drift operational amplifier in the Signal_Chain category. The OPA2388 dual version provides two amplifier channels and supports true rail-to-rail input and output operation across the OPAx388 family. Precision parameters include +/-0.25 uV ultra-low offset voltage, +/-0.005 uV/degC offset voltage drift over temperature, and 140 dB common-mode rejection ratio for zero-crossover true RRIO operation.
Noise and dynamic specifications include 7.0 nV/sqrt(Hz) voltage noise density at 1 kHz, 140 nVpp low-frequency noise from 0.1 Hz to 10 Hz with no 1/f noise, 10 MHz gain bandwidth product, and 2 us settling time for a 1 V step to 0.01%. Recommended operating supplies are 2.5 V to 5.5 V single supply or +/-1.25 V to +/-2.75 V dual supply.
Package options are SOIC-8 at 4.90 mm x 3.90 mm and VSSOP-8 at 3.00 mm x 3.00 mm. Thermal data includes 120.0 degC/W junction-to-ambient resistance for SOIC-8 and 165 degC/W for VSSOP-8. The specified free-air temperature range is -40 degC to +125 degC.
