LTC2383HMS-16#TRPBF

Overview

The LTC2383HMS-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 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 for reduced dissipation

Applications

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

Procurement Notes

Verify the H-grade suffix indicates the –40°C to 125°C operating range and the MS package denotes the 16-lead plastic MSOP form factor. Confirm the #TRPBF suffix specifies tape and reel packaging. Ensure the external reference voltage is set between 2.4V and 2.6V to maintain specified accuracy.

Selection Notes

Select this component when high speed and low power are required simultaneously. The internal oscillator simplifies timing design compared to external clock options. The differential input architecture maximizes dynamic range. Verify that the host system supports the required SPI protocol and that the OVDD supply matches the digital logic levels.

Part Context

This part belongs to the LTC238X-16 SAR ADC family, which shares architectural similarities 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 maintain 16-bit resolution and similar pinouts.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult Analog Devices marketing for parts specified with wider operating temperature ranges if the H-grade limit is insufficient.
