channel, zero drift op amps with low noise and power, ground Single ADA4528-1 AD8638 ADA4638-1 ADA4522-1 sensing inputs, and rail-to-rail output, optimized for total AD8628 accuracy over time, temperature, and voltage conditions. The AD8538 wide operating voltage and temperature ranges, as well as the ADA4051-1 high open-loop gain and very low dc and ac errors make the Dual ADA4528-2 AD8639 ADA4522-2 devices well suited for amplifying very small input signals and AD8629 for accurately reproducing larger signals in a wide variety of AD8539 applications. ADA4051-2 Quad AD8630 ADA4522-4 The ADA4522-1/ADA4522-2/ADA4522-4 performance is specified at 5.0 V, 30 V, and 55 V power supply voltages. These devices operate over the range of 4.5 V to 55 V, and are excellent for applications using single-ended supplies of 5 V, 10 V, 12 V, and 30 V, or for applications using higher single supplies and dual supplies of ±2.5 V, ±5 V, and ±15 V. The ADA4522-1/ ADA4522-2/ADA4522-4 use on-chip filtering to achieve high immunity to electromagnetic interference (EMI). The ADA4522-1/ADA4522-2/ADA4522-4 are fully specified over the extended industrial temperature range of −40°C to +125°C and are available in 8-lead MSOP, 8-lead SOIC, 14-lead SOIC, and 14-lead TSSOP packages.
