MAX111BCPE+

Analog To Digital Converters (ADC) Overview

The MAX111BCPE+ is a low-cost, 2-channel, ±14-bit serial analog-to-digital converter (ADC) from Analog Devices/Maxim Integrated. It operates on a single +5V supply and supports differential inputs in the ±1.5V range or single-ended inputs from 0V to +1.5V. The device features 14-bit resolution plus sign and overrange bits, with a maximum sampling rate of 50 conversions per second. Supply current is 640µA during operation and reduces to 4µA in power-down mode. It utilizes an internal auto-calibration technique for offset and gain-error correction without external components. The part is housed in a 16-pin PDIP package and operates within a temperature range of 0°C to +70°C.

Analog To Digital Converters (ADC) Feature Summary

• Single +5V supply operation with low power consumption
• Internal auto-calibration for offset and gain-error correction
• Compatible with SPI, QSPI, and MICROWIRE serial interfaces
• 50Hz/60Hz line-frequency rejection capability

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 'C' indicates the commercial temperature range (0°C to +70°C) against the official datasheet. Confirm the manufacturer is Analog Devices Inc. or Maxim Integrated. Ensure the package type matches the required 16-pin DIP configuration for your PCB layout. Check for RoHS compliance status if required by your manufacturing standards.

Analog To Digital Converters (ADC) Selection Notes

Select the MAX111BCPE+ when a single +5V supply is available and differential or single-ended input ranges up to ±1.5V are sufficient. Choose this component over the MAX110 variant if bipolar supplies are not present in the system design. Consider the 50 S/s conversion speed and 14-bit resolution requirements for your application's precision needs.

Analog To Digital Converters (ADC) Part Context

This component belongs to the MAX110/MAX111 family of low-cost, high-resolution serial ADCs. The MAX111 variant is specifically designed for single-supply applications, distinguishing it from the dual-supply MAX110. Both share identical architectural features, including sigma-delta modulation and internal calibration, but differ in power supply requirements and input voltage ranges.

Analog To Digital Converters (ADC) Replacement Considerations

The MAX110BCPE+ serves as a functional substitute if the system provides both +5V and -5V supplies, offering identical performance characteristics with a wider input voltage range.
