MAX1169BEUD+T

Analog To Digital Converters (ADC) Overview

The MAX1169BEUD+T is a low-power, 16-bit successive-approximation analog-to-digital converter (ADC) housed in a 14-pin TSSOP package. It operates from a single +4.75V to +5.25V analog supply and accepts digital logic levels from +2.7V to +5.5V. The device features an internal 4MHz clock and a +4.096V reference, supporting sampling rates up to 58.6ksps with a signal-to-noise ratio of 90dB. It utilizes an I²C-compatible 2-wire serial interface capable of 400kHz fast mode and 1.7MHz high-speed mode. Four address select inputs allow up to 16 devices on the same bus. The part guarantees ±2 LSB integral nonlinearity over the -40°C to +85°C temperature range.

Analog To Digital Converters (ADC) Feature Summary

• Integrated AutoShutdown™ functionality reduces power consumption significantly between conversions.
• Flexible dual-supply architecture allows direct interfacing with various digital logic voltage levels.
• On-chip track-and-hold circuitry supports unipolar conversion on a single analog input channel.

Analog To Digital Converters (ADC) Applications

• Hand-held portable applications
• Medical instruments
• Battery-powered test equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix 'T' indicates tape-and-reel packaging when sourcing this component. Confirm that the specific 'B' grade variant meets the required ±2 LSB INL specification for your design. Ensure the supplier provides documentation confirming RoHS compliance and lead-free status as indicated by the '+' designation.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution is required with minimal external reference components. The separate AVDD and DVDD supplies facilitate noise isolation for sensitive analog circuits. Consider the source impedance limitations; keep the analog input source resistance below 2kΩ for high-speed operation to ensure proper track-and-hold acquisition time.

Analog To Digital Converters (ADC) Part Context

This device belongs to the MAX1169 family of 16-bit serial ADCs. It is pin-compatible with the 14-bit MAX1069. The BEUD+T designation specifies the extended industrial temperature range, TSSOP package, and reel packaging format within the Maxim Integrated product line.

Analog To Digital Converters (ADC) Replacement Considerations

The MAX1069 is a pin-compatible alternative offering 14-bit resolution. For multi-channel requirements, consider the MAX11600 series or MAX11628 series which provide multiple input channels and different interface options.
