The MAX74810 is a dual-channel, zero drift op amp with low noise and power, ground sensing inputs, and rail-to-rail output, optimized for total accuracy over time, temperature, and voltage conditions. The wide operating voltage and temperature ranges, as well as the high open-loop gain and very low DC and AC errors, make the devices suitable for amplifying very small input signals and for accurately reproducing larger signals in a wide variety of applications.
The MAX74810 performance is specified at 5.0V and 50V power supply voltages. These devices operate over the range of 4.5V to 50V, and are excellent for applications using single-ended supplies of 5V, 10V, 12V, and 30V, or for applications using higher single supplies and dual supplies of ±2.5V, ±5V, and ±15V. The MAX74810 uses on-chip filtering to achieve high immunity to electromagnetic interference (EMI).
The MAX74810 is fully specified over the extended industrial temperature range of −40°C to +125°C and is available in an 8-lead MSOP package.
