LTC2383CDE-16#TRPBF

Overview

The LTC2383CDE-16#TRPBF is a 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices Inc. It operates from a single 2.5V supply and features a fully differential input range of ±2.5V. The device achieves a throughput rate of 1Msps with no cycle latency, consuming 13mW at full speed and 13µW in power-down mode. Key electrical specifications include a maximum integral nonlinearity (INL) of ±2LSB, guaranteed 16-bit resolution without missing codes, and a typical signal-to-noise ratio (SNR) of 92dB. It utilizes an SPI-compatible serial interface supporting 1.8V to 5V logic levels.

Feature Summary

• 16-bit resolution with guaranteed no missing codes and ±2LSB max INL
• 1Msps sampling rate with internal oscillator and zero cycle latency
• Low power consumption: 13mW at 1Msps, scaling down to 13µW in power-down mode
• SPI-compatible serial interface with daisy-chain support for 1.8V to 5V I/O voltages

Applications

• Medical imaging systems
• High-speed data acquisition
• Portable or compact instrumentation
• Industrial process control
• Low power battery-operated instrumentation

Procurement Notes

Verify the #TRPBF suffix indicates tape and reel packaging when sourcing this component. Confirm the specific grade suffix (e.g., C for commercial, I for industrial, H for extended temperature) matches the required operating temperature range, as the base model number does not specify thermal limits. Ensure the DFN package variant aligns with PCB layout constraints.

Selection Notes

Select the LTC2383CDE-16#TRPBF for applications requiring high-speed 16-bit conversion with low power dissipation. The external reference requirement necessitates pairing with a low-noise voltage reference such as the LTC6652-2.5. Consider the fully differential input architecture for noise rejection; if single-ended inputs are present, integrate a driver like the LT6350 for conversion. Verify that the host system supports the SPI-compatible serial interface timing requirements.

Part Context

This component belongs to the LTC238X-16 SAR ADC family, which includes variants with different throughput rates. The LTC2382-16 offers 500ksps at 6.5mW, while the LTC2381-16 provides 250ksps at 3.25mW. All family members share the same 16-bit resolution and architectural features but differ in speed and power consumption profiles.
