Initial Tolerance (A grade) Wide Operating Current Range Low Voltage Reference 2.5V Max. 0.6Ω Dynamic Impedance (A grade) Low Temperature Coefficient AMS1009 VOLTAGE REFERENCE DIODE APPLICATIONS Power Supplies Instrumentation 8 Bit A/D, D/A Reference Current Loop Measurement and Control Systems Reference for 5V Systems GENERAL DESCRIPTION The AMS1009 is a precision band-gap voltage reference diode. This 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 adjusted to ±5% to calibrate out system errors. The AMS1009 is 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 AMS1009 is available in TO-92 and SO-8 packages operating over a 0°C to 70°C temperature range. ORDERING INFORMATION: TOL.
