New device completes Microchip’s family of Vref products providing increased reliability and AEC-Q100 qualification

To have high reliability and performance along with low drift, voltage reference ICs with an extended-temperature range are needed for automotive, industrial and aerospace applications. Now with the new MCP1502, an automotive-qualified high-precision voltage reference (Vref) IC from Microchip Technology, the above needs can be met at a cost-effective price.

Based on the already proven MCP1501 Vref architecture, the MCP1502 is an AEC-Q100 Grade 1 (-40°C to +125°C operating temperature range) automotive-qualified Vref with a maximum temperature coefficient of 7ppm/°C. Microchip’s MCP150x (MCP1501 and MCP1502) devices are perfect companions to Microchip’s families of microcontrollers, ADCs and DACs, offering multiple voltage options for creating complete system solutions that are suitable for a wide variety of applications that require stable, accurate and repeatable data conversion.

“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.”

Packaged in a small six-lead SOT-23, the MCP1502 is available in voltage level options from 1V to 4V. Products can be obtained now via Microchip’s website or Microchip authorised distributor.
