MAX1285BCSA

Analog To Digital Converters (ADC) Overview

The MAX1285BCSA+ is a single-channel, 12-bit successive-approximation analog-to-digital converter (ADC) designed for low-power, single-supply applications. It operates from a +2.7V to +3.6V supply and features an internal +2.5V reference. The device supports sampling rates up to 300ksps with a serial interface compatible with SPI/QSPI/MICROWIRE protocols. Key electrical specifications include ±1 LSB maximum DNL and INL, a full-scale input range of 0 to VREF, and a typical supply current of 2.5mA during operation. It is housed in an 8-pin SO package and functions within a commercial temperature range of 0°C to +70°C.

Analog To Digital Converters (ADC) Feature Summary

Integrates a high-bandwidth track/hold amplifier and a 12-bit SAR ADC core on a single chip.
Includes a factory-trimmed internal voltage reference eliminating the need for external components.
Features a flexible 3-wire serial interface that connects directly to microprocessors without additional logic.
Provides a dedicated shutdown pin to significantly reduce power consumption between conversions.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'BCSA' corresponds to the commercial temperature grade (0°C to +70°C) and SOIC-8 package when sourcing replacements. Confirm RoHS compliance status as indicated by the '+' designation in the part number. Ensure the supply voltage rails match the +2.7V to +3.6V requirement, distinguishing this model from the MAX1284 variant which requires higher voltages.

Analog To Digital Converters (ADC) Selection Notes

Select the MAX1285BCSA+ when system power constraints require operation below 3.6V, as opposed to the MAX1284 series which requires 4.5V to 5.5V. This component is suitable for designs needing moderate speed (300ksps) with high linearity accuracy. Consider the internal reference capability if board space is limited, but ensure adequate bypass capacitance is maintained at the REF pin for stability.

Analog To Digital Converters (ADC) Part Context

This component belongs to the MAX1284/MAX1285 family of serial ADCs. It serves as a lower-voltage counterpart to the MAX1284, sharing identical pinouts and functional interfaces while optimizing for battery-operated environments. The 'B' indicates an upgraded speed version compared to earlier MAX124x series devices, offering higher throughput within the same compact 8-pin form factor.
