MAX110ACWE

Analog To Digital Converters (ADC) Overview

The MAX110ACWE+ 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 14-bit resolution plus overrange without external components. The device operates with ±5V supplies and converts differential analog signals in the -3V to +3V range. Operating supply current is 550µA, reducing to 4µA in power-down mode. It features a fast serial interface compatible with SPI, QSPI, and MICROWIRE standards. The component is housed in a 16-pin Wide SO package and supports an operating temperature range of 0°C to +70°C.

Analog To Digital Converters (ADC) Feature Summary

• Internal auto-calibration for offset and gain-error correction under microprocessor control
• Sigma-delta architecture providing 14-bit resolution plus sign and overrange bits
• Fast serial interface simplifies signal routing and opto-isolation while saving microcontroller pins
• Low power consumption suitable for battery-powered or remote-sensing applications

Analog To Digital Converters (ADC) Applications

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

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and temperature range. Ensure compatibility with existing system voltage requirements, as this model requires dual ±5V supplies. Confirm that the serial interface timing aligns with the host microcontroller's SPI or MICROWIRE configuration before finalizing procurement.

Analog To Digital Converters (ADC) Selection Notes

Select the MAX110ACWE+ when dual ±5V power supplies are available and high-resolution differential input conversion is required. This part is appropriate for applications needing internal calibration to minimize external component count. Consider the MAX111 variant if only a single +5V supply is present, as it handles unipolar inputs differently. Verify that the 50 conversions per second rate meets the system's data throughput requirements.

Analog To Digital Converters (ADC) Part Context

The MAX110ACWE+ belongs to the MAX110/MAX111 family of low-cost, 2-channel, ±14-bit serial ADCs. These devices are designed for high-resolution applications where low power consumption and minimal external circuitry are critical. The AC suffix indicates a commercial temperature grade (0°C to +70°C), while the WE suffix denotes the 16-pin Wide SO package format.

Analog To Digital Converters (ADC) Replacement Considerations

Public confirmed substitute part numbers include MAX110BCWE+, which offers similar specifications within the same package and temperature range.
