MAX4236 - Maxim

MAX4236 SOT23 / Very High Precision / 3V/5V Rail-to-Rail Op Amps

The MAX4236/MAX4237 are high-precision op amps that feature an exceptionally low offset voltage and offset voltage temperature coefficient without using any chopper techniques. The MAX4236 and MAX4237 have a typical large-signal, open-loop voltage gain of 120dB. These devices have an ultra-low input-bias current of 1pA. The MAX4236 is unity-gain stable with .

Features

make the amplifiers ideal for applications with +3V or +5V single power supplies. The MAX4236/MAX4237 are specified for the extended temperature range (-40°C to +85°C) and are available in tiny SOT23, µMAX, and SO packages. For greater accuracy, the A grade µMAX and SO packages are tested to guarantee 20µV (max) offset voltage at +25°C and less then 2µV/°C drift. Features o Ultra-Low Offset Voltage 20µV (max) at +25°C (Grade A) 50µV (max) at +25°C (Grade B, 6-Pin SOT23) o Ultra-Low Offset Voltage Drift 2µV/°C (max) (Grade A) 4.5µV/°C (max) (Grade B, 6-Pin SOT23) 5.5µV/°C (max) (6-Pin SOT23) o.
