SOT23, Very High Precision, 3V/5V
Rail-to-Rail Op Amps
General Description
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 a gainbandwidth product of 1.7MHz, while the MAX4237 is stable for closed-loop gains greater than 5V/V with a gain-bandwidth product of 7.5MHz. Both devices have a shutdown function in which the quiescent current is reduced to less than 0.1µA, and the amplifier output is forced into a high-impedance state.
The input common-mode range of the MAX4236/ MAX4237 extends below the negative supply range, and the output swings Rail-to-Rail®. These 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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

Note 1: All devices are 100% production tested at TA = +25°C; all specifications over temperature are guaranteed by design, unless otherwise specified.
Note 2: Guaranteed by design, not production tested.
Note 3: Maxim specification limits for the temperature coefficient of the offset voltage (TCVOS) are 100% tested for the A-grade, 8- pin SO and µMAX packages.
