EL2125CSZ-T7

Overview

The EL2125CSZ-T7 is a high-speed, low-noise operational amplifier manufactured by Renesas Electronics. It features a single channel with a slew rate of 185 V/us and a voltage gain of 87 dB. The device operates within a supply voltage range of 5 V to 33 V (or ±2.5 V to ±15 V) and consumes 11 mA of operating current. Key electrical specifications include an input offset voltage of 2 mV, input bias current of 22 uA, CMRR of 80 dB, and PSRR of 80 dB. Noise performance is characterized by an input voltage noise density of 0.83 nV/sqrt Hz and input noise current density of 3.4 pA. It is housed in an SOIC-8 package and functions within a temperature range of -40 C to +85 C.

Procurement Notes

Verify component authenticity through authorized distributors as the part status is listed as obsolete. Confirm RoHS compliance details via official datasheets before integration. Ensure handling procedures account for moisture sensitivity classification during storage and assembly processes to maintain device reliability.

Selection Notes

Select this component when high slew rate and low noise are critical requirements for single-channel amplification. Consider the SOIC-8 package constraints and thermal management needs for the specified operating temperature range. Evaluate power supply stability given the 11 mA quiescent current draw and wide voltage tolerance.
