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 400 µ A 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.
