MCP1502 High-Precision Voltage Reference IC

Microchip Technology Inc. has announced the release of a high-precision voltage reference (Vref) IC for automotive and industrial applications which require low drift, high reliability, and high performance. The new MCP1502 is an AEC-Q100 Grade 1 automotive-qualified Vref with a maximum temperature coefficient of 7ppm/°C and -40°C to +125°C operating temperature range. Packaged in a small six-lead SOT-23, the MCP1502 IC is an ideal choice for a wide variety of industrial, automotive, and aerospace applications that require a high level of reliability.

The MCP1502 IC features an initial accuracy of 0.10% and is available in 8 voltage options. This low-drift (7ppm max) bandgap-based reference uses copper-based amplifiers which significantly reduce the drift and provides high current output. Moreover, the MCP1502 IC is available in the most popular voltage level options from 1V to 4V.
