AD8253 is a 10MHz, 20V/μs, G=1, 10, 100, 1000 iCMOS programmable gain instrumentation amplifier with small package, programmable gain, digital or pin programmable, wide power supply voltage, excellent DC performance, high common mode rejection ratio (CMRR), low gain drift, low offset drift, excellent AC performance, 0.001% fast settling time, high slew rate, low distortion, frequency-dependent high common mode rejection ratio (CMRR), low noise etc.
The AD8253 is a programmable instrumentation amplifier designed for data‑acquisition, biomedical analysis, and test‑and‑measurement applications. It features a 10 MHz bandwidth, low total harmonic distortion (‑110 dB THD), and fast settling time (780 ns). The device operates from a wide supply range (±5 V to ±15 V) and provides high common‑mode rejection (≥100 dB at 20 kHz, G=1000).
Key features include four gain settings (1, 10, 100, 1000) selectable via digital pins or a parallel interface, low input‑bias current, low offset drift (10 ppm/°C), low voltage noise (10 nV/√Hz at G=1000), and a compact 10‑pin MSOP package suitable for space‑constrained designs.
