LTC1604CG#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1604CG#TRPBF is a high-speed, 16-bit sampling analog-to-digital converter (ADC) from Analog Devices. It operates at a maximum sampling rate of 333ksps with a typical power dissipation of 220mW from ±5V supplies. The device features a true differential input sample-and-hold with a ±2.5V full-scale range and a 15MHz bandwidth. Key performance metrics include 90dB S/(N+D) and –100dB THD at the maximum sample rate. It integrates a precision internal reference and offers two digitally selectable shutdown modes: Nap (7mW) and Sleep (10μW). The component utilizes a μP-compatible 16-bit parallel output interface without pipeline delay.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific 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. Ensure compatibility with ±5V supply requirements for both analog and digital sections.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring high linearity and low distortion at moderate speeds. The integrated 2.5V reference simplifies design but requires a 47μF capacitor on the REFCOMP pin for stability in sleep mode wake-up. Consider source impedance limitations; high impedance sources may require buffering to meet the 480ns acquisition time specification.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1604 family of 16-bit ADCs. The CG suffix denotes the plastic SSOP-36 package variant. Other variants include the I grade for industrial temperature ranges (-40°C to 85°C) and A grade for tighter linearity specifications. The device is designed for direct interfacing with microprocessors and DSPs via its parallel data bus.
