LTC1609IG#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1609IG#TRPBF is a 16-bit, 200ksps serial sampling analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It operates from a single 5V supply and dissipates 65mW typically. The device integrates a sample-and-hold circuit, precision reference, switched-capacitor successive approximation A/D, and trimmed internal clock. It supports multiple input ranges: unipolar (0V to 10V, 0V to 5V, 0V to 4V) and bipolar (–10V, –5V, –3.3V). Key electrical specifications include a typical signal-to-noise ratio of 87dB, guaranteed no missing codes over temperature, and an integral nonlinearity error of –2LSB. The component is housed in a 20-lead SOIC package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix #TRPBF indicates tape and reel packaging. Confirm the 'I' grade designation corresponds to the industrial temperature range of –40°C to 85°C. Ensure compatibility with the 20-lead SOIC footprint during procurement planning.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit SAR ADC with serial interface is required for single-supply 5V systems. Consider the specific input range requirements (unipolar vs. bipolar) as pin connections vary. Verify that the 200ksps throughput meets system timing constraints. Check if the integrated 2.5V reference suffices or if an external reference is needed for higher accuracy.

Analog To Digital Converters (ADC) Part Context

The LTC1609 is part of Linear Technology's (now Analog Devices) family of serial sampling ADCs. It serves as an improved second source for the ADS7809 and AD977A. The device is designed for applications requiring moderate speed and high resolution without complex parallel interfaces.

Analog To Digital Converters (ADC) Replacement Considerations

The datasheet identifies the LTC1609 as an improved second source for the ADS7809 and AD977A. Verify pinout and electrical parameter compatibility before substituting these legacy parts.
