LTC1609CG#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1609CG#TRPBF is a 16-bit, 200ksps serial sampling Analog-to-Digital Converter (ADC) from Analog Devices Inc. It operates on a single 5V supply and dissipates 65mW typically. The device integrates a sample-and-hold circuit, a precision internal reference, a switched-capacitor successive approximation A/D converter, and a 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 (SNR) of 87dB, guaranteed no missing codes over temperature, and an integral nonlinearity error of -2LSB maximum.

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the 'C' grade designation corresponds to the commercial operating temperature range of 0°C to 70°C as specified in the datasheet. Ensure compatibility with the 20-pin SO package format associated with this specific part number variant.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC1609CG#TRPBF for applications requiring 16-bit accuracy at moderate speeds without external clocking or reference components. Choose this part if the system requires a single 5V supply and benefits from integrated offset/gain trim capabilities via R1IN, R2IN, and R3IN pins. Consider the 200kHz throughput limit and 87dB SNR performance against application noise requirements.

Analog To Digital Converters (ADC) Part Context

The LTC1609 series serves as an improved second source for legacy parts like the ADS7809 and AD977A. It belongs to Linear Technology's family of serial sampling ADCs designed for ease of interface with microprocessors and DSPs through its simple serial I/O protocol. The CG variant specifically denotes the commercial temperature grade within the 20-pin SO package lineup.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed direct substitutes listed in the datasheet are the ADS7809 and AD977A. Verify pinout compatibility and electrical parameter alignment before substitution.
