With 120dB minimum open-loop gain, 110dB minimum CMRR and PSRR, and only 1.2nA typical input bias current, the OP177 delivers unmatched DC accuracy for the most demanding instrumentation and measurement applications. The device operates from +\/-3V to +\/-18V supplies and consumes only 1.6mA typical supply current. The GS suffix denotes SOIC-8 package and REEL7 indicates tape and reel packaging with 1000 units per reel.","working_principle":"The OP177GSZ-REEL7 operates as a precision bipolar operational amplifier. (1) The input stage uses a super-beta transistor differential pair with laser-trimmed resistors to achieve the 10uV maximum offset voltage, eliminating the need for external nulling in most applications. (2) The high 120dB open-loop gain is achieved through a three-stage amplifier architecture with carefully balanced gain distribution, ensuring that closed-loop accuracy is not degraded by finite gain effects. (3) The 110dB CMRR is achieved through tight matching of input pair collector resistors and constant-current biasing, while the 110dB PSRR results from internal supply regulation and balanced circuit topologies.","pin_description":"
