With an offset voltage of 2.5 V, offset voltage drift of 0.015 V/C, and typical noise of 97 nV p-p (0.1 Hz to 10 Hz, A = +100), the ADA4528-1/ADA4528-2 are well suited for V applications in which error sources cannot be tolerated. The ADA4528-1/ADA4528-2 have a wide operating supply range 1 of 2.2 V to 5.5 V, high gain, and excellent CMRR and PSRR specifi- 1 100 1k 10k 100k 1M 10M 10 cations, which make it ideal for applications that require precision Figure 3.
