Laser-trimmed thin-film resistors provide excellent long-term voltage offset stability and allow superior voltage offset compared to common zener-zap techniques. A unique bias current cancellation circuit allows bias and offset current specifications to be met over the full –55°C to +125°C temperature range. The OPA27 is internally compensated for unity-gain stability. The decompensated OPA37 requires a closedloop gain ≥ 5. The Burr-Brown OPA27/37 is an improved replacement for the industry-standard OP-27/OP-37. 2 –In 3 +In 8 Trim 1 Trim +VCC 6 Output 4 –VCC International Airport Industrial Park Mailing Address: PO Box 11400, Tucson, AZ 85734 Street Address: 6730 S.
