Product details

12-bit SAR ADC with flexible input mux

The MAX1203BEAP+ is a 12-bit successive-approximation ADC from Analog Devices, built around a MUX-S/H-ADC architecture that accepts either 4 differential or 8 single-ended inputs through the on-chip multiplexer. Sampling at 133k samples per second, it delivers the throughput needed for industrial sensor acquisition, data-logging front ends, and battery-monitoring channels where 12-bit resolution is the sweet spot between cost and accuracy. The SPI digital interface keeps the pin count low and ties directly to most microcontrollers without glue logic.

Industrial temperature range and package

Rated for -40°C to 85°C, the MAX1203BEAP+ fits industrial enclosures, outdoor telecom cabinets, and engine-bay-adjacent electronics where the ambient can swing. The 20-pin SSOP (0.209" body width, 5.30 mm) is a surface-mount footprint that saves board area compared to a wider SOIC, and the tube shipping medium is typical for prototype and low-to-mid volume builds.

Sourcing and lifecycle

For a BOM line that needs a 12-bit SAR ADC with SPI and a flexible input mux, the MAX1203BEAP+ is a safe choice for new designs and production ramp.

Frequently asked questions

Is MAX1203BEAP+ obsolete or active?

MAX1203BEAP+ is active in production with no end-of-life notice. It is suitable for new designs and production builds.

What are the exact specifications of MAX1203BEAP+?

The MAX1203BEAP+ is a 12-bit SAR ADC sampling at 133k samples per second. It accepts 4 differential or 8 single-ended inputs through an internal mux, communicates via SPI, operates on ±5V or 5V analog supply with a 2.7V to 5.25V digital supply, and is rated for -40°C to 85°C in a 20-SSOP package.

What is MAX1203BEAP+'s listed input type?

The input type is both differential and single-ended, selectable via the internal multiplexer. The part supports 4 differential or 8 single-ended inputs.
