The MAX4236/MAX4237 are high-precision op amps that feature an exceptionally low offset voltage and off- set voltage temperature coefficient without using any chopper techniques.
The MAX4236 and MAX4237 are high‑precision CMOS op‑amps featuring ultra‑low offset voltage, low offset‑temperature coefficient and a 1 pA input‑bias current. They operate from a single‑supply voltage of +2.4 V to +5.5 V (or ±1.2 V to ±2.75 V) and provide rail‑to‑rail output swing, making them suitable for precision sensor and instrumentation applications.
Key features include a gain‑bandwidth product of 1.7 MHz (MAX4236) or 7.5 MHz (MAX4237), shutdown current of only 0.1 µA, ultra‑low offset (20 µV max for grade A), and the ability to drive loads up to 200 pF while maintaining stability.
