1 / 8 page Date: 11/05/04 SPX385-1.2 Micropower Voltage Reference © Copyright 2004 Sipex Corporation 1 FEATURES ■ Low Output Voltage ................................ 1.235V ■ Dynamic Impedance...............................1Ω max ■ Low Temperature Coefficient........30ppm/°C (typ) ■ Operating Current ........................ 10µA to 20mA ■ Extended Temperature Range .. -40°C to +85°C ■ Initial Tolerance..................................1% and 2% ■ Pin Compatible with LM185/285/385, 1.23V Micropower Voltage Reference SPX385-1.2 The SPX385-1.2 is a micropower 2-terminal band-gap voltage reference with a very wide operating current range from 10µA to 20mA that provides a stable voltage. The high stability of this device is primarily the result of the low temperature coefficient Thin Film Resistor process and Laser Trimming of the output voltage at the wafer level. The SPX385-1.2 is available in a TO-92, SOIC-8 and SOT-89 package with an operating temperature range of -40°C to 85°C. A 2.5 and 5.0 volt devices are also available - SPX385-2.5, SPX385-5.0. ® Figure 1: Block Diagram APPLICATIONS ■ Portable Meter Reference ■ Portable Test Instruments ■ Battery Operated Systems ■ Panel Meters 1.235V + - Cathode (K) Anode (A) DESCRIPTION BLOCK DIAGRAM Now Available in Lead Free Packaging 1 2 3 4 5 6 7 8 SPX385-1.2 8 Pin nSOIC CATHODE N/C ANODE N/C N/C N/C N/C N/C |
