LTC2383IDE-16#PBF

Overview

The LTC2383IDE-16#PBF 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 with a ±2.5V fully differential input range and consumes 13mW at a 1Msps throughput rate. The device features an SPI-compatible serial interface supporting 1.8V to 5V logic levels, daisy-chain mode, and an internal conversion clock. Key performance metrics include ±2LSB maximum integral nonlinearity, guaranteed 16-bit no missing codes, and a typical signal-to-noise ratio of 92dB. The component is housed in a 16-lead 4mm × 3mm plastic DFN package and supports an operating temperature range of –40°C to 85°C.

Feature Summary

• 16-bit resolution with 1Msps sampling rate and 13mW power consumption
• ±2.5V fully differential input range with external 2.5V reference requirement
• SPI-compatible serial interface with 1.8V to 5V I/O voltage support
• Internal oscillator for conversion timing with auto power-down capability

Applications

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

Procurement Notes

Verify the specific ordering suffix #PBF indicates lead-free finish and tape and reel availability if required. Confirm the IDE suffix corresponds to the industrial temperature grade (–40°C to 85°C) and the DE package type (16-lead 4mm × 3mm Plastic DFN). Ensure compatibility with the required 2.5V analog supply and appropriate digital I/O voltage levels before procurement.

Selection Notes

Select this part when a low-power, high-speed 16-bit SAR ADC with a fully differential input is required. The internal oscillator simplifies timing design compared to external clock options. Consider the H-grade variant if operation up to 125°C is necessary. Ensure the application can accommodate the external reference voltage requirement and the specific DFN package footprint constraints.

Part Context

This component belongs to the LTC238X-16 SAR ADC family, which includes variants with different throughput rates such as the LTC2382-16 (500ksps) and LTC2381-16 (250ksps). The LTC2383-16 represents the highest speed option in this specific resolution class within the series, offering 1Msps throughput while maintaining low power dissipation characteristics suitable for portable applications.
