LTC2383IDE-16#TRPBF

Overview

The LTC2383IDE-16#TRPBF is a 16-bit, 1Msps successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices Inc. It operates from a single 2.5V supply with a ±2.5V fully differential input range and consumes 13mW at full throughput. The device features an SPI-compatible serial interface supporting 1.8V to 5V logic levels and includes a daisy-chain mode. Key performance metrics include ±2LSB maximum integral nonlinearity, guaranteed 16-bit no missing codes, and 92dB typical SNR. This specific part number denotes the industrial temperature grade (-40°C to 85°C) in a 16-lead 4mm × 3mm plastic DFN package, supplied in tape and reel format.

Feature Summary

• 16-bit resolution with 1Msps sampling rate and no pipeline delay or cycle latency
• Low power consumption of 13mW at 1Msps, scaling down to 13µW at 1ksps via auto power-down
• SPI-compatible serial I/O with daisy-chain capability, supporting 1.8V, 2.5V, 3.3V, and 5V logic
• Guaranteed 16-bit no missing codes with ±2LSB max INL and 92dB typical SNR

Applications

• Medical imaging systems
• High-speed data acquisition
• Portable or compact instrumentation
• Industrial process control
• Automated test equipment (ATE)

Procurement Notes

Verify that the #TRPBF suffix confirms the tape and reel packaging configuration for automated assembly. Ensure the IDE designation matches the required -40°C to 85°C industrial operating temperature range for the target application environment.

Selection Notes

Select this component when a low-power, high-speed 16-bit SAR ADC with a fully differential input is required. The internal oscillator simplifies timing design, while the auto power-down feature optimizes energy efficiency for battery-operated devices. Ensure the host system supports the SPI-compatible serial interface and provides the necessary 2.5V analog and 1.8V–5V digital supplies.

Part Context

This part belongs to the LTC238X-16 SAR ADC family, which includes variants with different speeds and power profiles such as the LTC2382-16 (500ksps) and LTC2381-16 (250ksps). The LTC2383-16 represents the highest speed option within this specific 16-bit series, offering 1Msps throughput while maintaining low power dissipation.

Replacement Considerations

Direct pin-compatible replacements within the same package and electrical specifications are not explicitly listed in the provided documentation. Other members of the LTC238X-16 family share similar interfaces but differ in speed and power.
