LTC1604CG#PBF

Analog To Digital Converters (ADC) Overview

The LTC1604CG#PBF is a 16-bit, 333ksps sampling analog-to-digital converter (ADC) housed in a 36-lead plastic SSOP package. It operates from ±5V supplies with a typical power dissipation of 220mW. The device features a high dynamic range sample-and-hold circuit, a precision internal reference, and a 16-bit parallel output interface. Key performance metrics include a signal-to-noise-plus-distortion ratio of 90dB and total harmonic distortion of –100dB at the maximum sampling rate. It supports two digitally selectable power shutdown modes: Nap (7mW) and Sleep (10μW).

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific grade suffix 'C' indicates the commercial temperature range (0°C to 70°C). Confirm the '#PBF' suffix denotes lead-free packaging compliant with RoHS standards. Cross-reference the manufacturer's latest documentation for any potential product discontinuation notices or pinout revisions before finalizing procurement plans.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring high linearity and low power consumption without pipeline latency. Ensure the system can provide ±5V analog supplies and a separate digital supply (OVDD) if interfacing with 3V logic. Verify that the source impedance allows for the specified 480ns acquisition time or implement buffering for higher impedance sources.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1604 family of high-speed SAR ADCs. The 'CG' designation specifies the 36-lead SSOP package and the 'C' grade for commercial operating temperatures. It serves as a parallel-output alternative to serial-interface models within the Analog Devices portfolio, designed for direct microprocessor connection.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate other members of the LTC1604 family, such as the LTC1604A for improved linearity specifications, ensuring package compatibility and electrical parameter alignment.
