1000_GAIN_AT_2_kHz

Uses Harris HA-2900 chopper-stabilized opamp. Either input terminal may be grounded, giving choice of inverting or noninverting operation, or inputs may be driven differentially. Symmetrical input networks eliminate chopper noise, limiting total input noise to about 30μ VRMS when C is 0. Noise can be further reduced, at expense of bandwidth, by adding optional capacitors C as shown. Without these capacitors, bandwidth is 2 kHz.- Linear & Data Acquisition Products, Harris Semiconductor, Melbourne, FL, Vol. 1, 1977, p 7-69 (Application Note 518).
