The OP177 features one of the highest precision performance ofany operational amplifier currently available. Offset voltage of theOP177 is only 25 μV maximum at room temperature. The ultralowVOS of the OP177 combines with the exceptional offset voltagedrift (TCVOS) of 0.3 μV/°C maximum to eliminate the need forexternal VOS adjustment and increases system accuracy overtemperature.The OP177 open-loop gain of 12 V/μV is maintained over the full±10 V output range. CMRR of 130 dB minimum, PSRR of 120 dBminimum, and maximum supply current of 2 mA are just a fewexamples of the excellent performance of this operational amplifier.The combination of outstanding specifications of the OP177ensures accurate performance in high closed-loop gainapplications. This low noise, bipolar input operational amplifier is also a costeffective alternative to chopper-stabilized amplifiers. The OP177provides chopper-type performance without the usual problemsof high noise, low frequency chopper spikes, large physical size,limited common-mode input voltage range, and bulky externalstorage capacitors.The OP177 is offered in the −40°C to +85°C extended industrialtemperature ranges. This product is available in 8-lead PDIP, aswell as the space saving 8-lead SOIC.

The OP249 is a high speed, precision dual JFET op amp, similar to the popular single op amp. The OP249 outperforms available dual amplifiers by providing superior speed with excellent dc performance. Ultrahigh open-loop gain (1 kV/mV minimum), low offset voltage, and superb gain linearity makes the OP249 the industry’s first true precision, dual high speed amplifier.With a slew rate of 22 V/μs typical and a fast settling time of less than 1.2 μs maximum to 0.01%, the OP249 is an ideal choice for high speed bipolar DAC and ADC applications. The excellent dc performance of the OP249 allows the full accuracy of high resolution CMOS DACs to be realized. Symmetrical slew rate, even when driving large load, such as, 600 Ω or 200 pF of capacitance and ultralow distortion, make the OP249 ideal for professional audio applications, active filters, high speed integrators, servo systems, and buffer amplifiers.Applications Output amplifier for fast DACs Signal processing Instrumentation amplifiers Fast sample-and-holds Active filters Low distortion audio amplifiers Input buffer for ADCs Servo controllers
