Using advanced geometry ® +V CC dielectrically-isolated FET (Difet ) inputs, this mono- lithic amplifier achieves a performance level exceed- ing even the best hybrid electrometer amplifiers. –In Laser-trimmed thin-film resistors give outstanding volt- 2 age offset and drift performance. 3 A noise-free cascode and low-noise processing give Noise-Free +In the OPA128 excellent low-level signal handling capa- Cascode 6 bilities. Flicker noise is very low. Output The OPA128 is an improved pin-for-pin replacement for the AD515. 28kΩ 28kΩ Trim 1kΩ 1 ® Difet Burr-Brown Corp. 5 1kΩ Trim 2kΩ 2kΩ 4 –V CC OPA128 Simplified Circuit International Airport Industrial Park • Mailing Address: PO Box 11400, Tucson, AZ 85734 • Street Address: 6730 S.
