LTC2383HMS-16#PBF

Overview

The LTC2383HMS-16#PBF 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 H-grade variant supports an operating temperature range of –40°C to 125°C and is housed in a 16-lead plastic MSOP package.

Feature Summary

• 16-bit resolution with 1Msps sampling rate and 13mW power consumption
• ±2LSB max INL, guaranteed 16-bit no missing codes, and 92dB typical SNR
• SPI-compatible serial interface with daisy-chain capability for 1.8V–5V I/O
• Internal oscillator and auto power-down functionality

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 H-grade designation matches the required –40°C to 125°C operating temperature range for the target application environment. Ensure the 16-lead MSOP package dimensions align with the PCB footprint constraints.

Selection Notes

Select this component when a high-speed 16-bit SAR ADC with low power dissipation is required. The H-grade version is necessary for applications operating between –40°C and 125°C. Consider the internal oscillator and auto power-down features for simplified timing and energy efficiency. Ensure the external reference voltage is within the 2.4V to 2.6V range to maintain specified accuracy.

Part Context

This part belongs to the LTC238X-16 SAR ADC family, which shares similar architectural features but varies in speed and power. The LTC2383-16 represents the highest speed tier at 1Msps, while the LTC2382-16 offers 500ksps and the LTC2381-16 provides 250ksps. All variants in this series maintain 16-bit resolution and low power characteristics suitable for portable applications.

Replacement Considerations

For lower speed requirements, consider the LTC2382-16 (500ksps) or LTC2381-16 (250ksps). For DFN package options, the LTC2383IDE-16#PBF offers the same electrical performance in a 4mm × 3mm Plastic DFN package with an industrial temperature range.
