High-precision voltage reference IC provides very-low drift

Update: October 14, 2021

Microchip Technology has released a high-precision voltage reference (Vref) IC that satisfies the needs of extended temperature range voltage reference ICs for automotive and industrial applications requiring low drift, high reliability and high performance at a cost-effective price. The new MCP1502 is an AEC-Q100 Grade 1 (-40C to +125C operating temperature range) automotive-qualified Vref with a maximum temperature coefficient of 7ppm/C.

“Microchip looked at the top four aspects that customers were requesting in a Vref and made a product that combines high reliability, small package size and high performance at a very cost-effective price,” said Fanie Duvenhage, vice president of Microchip’s mixed-signal and linear devices business unit. “This combination of features at this price is unmatched by competitors, especially when you add our experience in serving customers in the automotive and aerospace industries who require robust products for harsh environments.”

The IC is based on the MCP1501 Vref architecture, available for more than five years. Packaged in a small six-lead SOT-23, it is an ideal option for an extensive variety of industrial, automotive and aerospace applications that need a high level of reliability. The MCP150x (MCP1501 and MCP1502) devices are ideal companions to the company’s families of microcontrollers, ADCs and DACs, providing multiple voltage options for producing total system solutions that are fitting for a wide variety of applications that need stable, accurate and repeatable data conversion. The device is available in the most popular voltage level options from 1V to 4V.
