GENERAL DESCRIPTION

The AMS236/AMS336 are precision band-gap voltage reference diodes. These voltage reference features a very low dynamic

impedance and good temperature coefficient, operating over a wide current range of 400µA to 10mA. On-chip trimming is

used to provide tight tolerance and minimize temperature drift. A third terminal allows the reference voltage to be trimmed

±5%.

The AMS236/AMS336 are used as a precision 2.5V low voltage reference for digital voltmeters, power supplies or op amp

circuitry, and the 2.5V make it easy to obtain a stable reference from 5V logic supplies.

The AMS236 is rated for operation over -25

°C to +85°C while the AMS336 is rated over a 0°C to 70°C temperature range.

The AMS236/AMS336 are available in TO-92 and SO-8 packages.
