MAX110BCWE+

Analog To Digital Converters (ADC) Overview

The MAX110BCWE+ is a low-cost, two-channel, ±14-bit serial analog-to-digital converter (ADC) manufactured by Analog Devices Inc./Maxim Integrated. It utilizes an internal auto-calibration technique to achieve high resolution without external components. The device operates with ±5V supplies and converts differential analog signals within the -3V to +3V range. Key electrical parameters include a 14-bit resolution plus sign and overrange bits, a maximum sampling rate of 50 conversions per second, and a typical supply current of 550µA at ±5V. It features SPI, QSPI, and MICROWIRE compatibility, 50Hz/60Hz rejection, and operates within a temperature range of 0°C to +70°C in a 16-pin Wide SO package.

Analog To Digital Converters (ADC) Feature Summary

• Internal auto-calibration for offset and gain-error correction under microprocessor control
• Dual differential input channels supporting high-resolution signal acquisition
• Low power consumption with dedicated shutdown mode reducing current to 4µA
• Serial interface compatible with standard SPI, QSPI, and MICROWIRE protocols

Analog To Digital Converters (ADC) Applications

• Process Control Systems
• Weigh Scales
• Panel Meters
• Data-Acquisition Systems
• Temperature Measurement

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'BCWE+' against the manufacturer's official datasheet to confirm the commercial temperature grade (0°C to +70°C) and the 16-pin Wide SOIC package type. Ensure that the required ±5V dual supply rails are available in the target design, as this component does not support single-supply operation unlike its MAX111 counterpart. Cross-reference the RoHS compliance status with the latest production documentation.

Analog To Digital Converters (ADC) Selection Notes

Select the MAX110BCWE+ when designing systems requiring dual-channel, high-precision conversion with a ±5V power architecture. This part is suitable for applications where low-frequency signals must be digitized with minimal external component count due to its integrated calibration. Consider the MAX111 variant if the system design mandates a single +5V supply instead of dual rails. Evaluate the 50 S/s sampling rate against the Nyquist requirements of the input signal bandwidth.

Analog To Digital Converters (ADC) Part Context

This component belongs to the MAX110/MAX111 family of low-cost, sigma-delta ADCs designed for battery-powered or remote-sensing applications. The MAX110 variant specifically supports dual-polarity supplies, distinguishing it from the single-supply MAX111. The family emphasizes space-saving packaging and simplified signal routing through its serial interface capabilities, targeting industrial instrumentation and data acquisition markets.
