Product details

Precision instrumentation amp for bridge and sensor conditioning

The Analog Devices AD8237ARMZ is a single-supply instrumentation amplifier in an 8-MSOP package, designed for precision sensor signal conditioning where low power and rail-to-rail output swing are required. It delivers a -3 dB bandwidth of 200 kHz with a slew rate of 0.15 V/µs, making it suitable for amplifying low-frequency signals from strain gauges, thermocouples, and medical sensors without sacrificing DC accuracy. Supply current is just 115 µA, which fits battery-powered or loop-powered transmitter designs.

Supply range and rail-to-rail output

Output drive capability is 4 mA per channel, sufficient to drive a typical ADC input or a reference buffer.

The supplier device package is 8-MSOP. For reflow assembly, note the MSOP lead pitch and pad geometry — standard MSOP-8 land patterns apply.

Frequently asked questions

What is the equivalent or replacement for AD8237ARMZ?

The AD8237ARMZ-R7 is the tape-and-reel variant of the same die. For a functionally similar instrumentation amplifier with higher bandwidth (250 kHz) and higher supply current (300 µA), consider the AD8227BRZ or AD8227ARZ, but note the different package and parametric trade-offs.
