The device achieves precision through a patented DigiTrim architecture: input offset voltage is trimmed to 40uV typical (100uV max over temperature) using digital correction at wafer sort. The input bias current is 0.2pA typical (200fA), achieved with a CMOS input stage. The CMOS input eliminates the bias current errors that plague bipolar op-amps in high-impedance sensor applications (pH probes, photodiodes). The gain-bandwidth product is 400kHz, and the slew rate is 0.4V\/us, making it suitable for DC and low-frequency signals. The rail-to-rail input stage uses two complementary differential pairs (N-ch and P-ch MOSFETs) that cover the full supply range. The transition between pairs occurs near mid-supply and is handled by a crossover circuit that minimizes distortion. The output swings to within 15mV of both rails at 1mA load, and to within 2mV at 100uA. The PSRR is 100dB at DC, and the CMRR is 100dB minimum. The offset voltage drift is 0.5uV\/C typical. The -AUJZ suffix specifies SOT-23-5, and -R2 specifies tape-and-reel packaging. The AD8603 is the single version of the dual AD8606 and quad AD8608. Applications include: battery-current sensing, photodiode transimpedance amplifiers, and pH electrode buffers.","pin_description":"
