LTC2383CMS-16#TRPBF

Overview

The LTC2383CMS-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 supports a ±2.5V fully differential input range. The device delivers a throughput rate of 1Msps with no pipeline delay or cycle latency, consuming 13mW at full speed. Key electrical specifications include a typical SNR of 92dB, ±2LSB maximum INL, and guaranteed 16-bit resolution without missing codes. It features an SPI-compatible serial interface supporting 1.8V to 5V logic levels and includes daisy-chain mode capability.

Feature Summary

• 16-bit resolution with 1Msps sampling rate and no cycle latency
• Low power consumption: 13mW at 1Msps, scaling down to 13µW at 1ksps
• Fully differential input range of ±2.5V with external 2.5V reference requirement
• SPI-compatible serial I/O supporting 1.8V, 2.5V, 3.3V, and 5V logic 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 ordering suffix #TRPBF confirms the tape and reel packaging format for automated assembly. Confirm the CMS suffix indicates the commercial temperature range of 0°C to 70°C. Ensure the component is sourced from authorized distributors to guarantee authenticity and adherence to lead-free specifications.

Selection Notes

Select this model when a 1Msps throughput is required alongside low power dissipation. The external reference input necessitates pairing with a precision voltage reference such as the LTC6652-2.5. Use the H-grade variant if operation above 70°C is needed. Ensure the host interface voltage matches the OVDD supply range of 1.71V to 5.25V.

Part Context

This component belongs to the LTC238X-16 SAR ADC family, which includes variants with different speeds and power profiles. The LTC2383-16 represents the high-speed, 1Msps option within this series. Other family members include the LTC2382-16 (500ksps) and LTC2381-16 (250ksps), offering lower power consumption at reduced sampling rates.

Replacement Considerations

Direct functional replacements within the same package and pinout include other LTC2383-16 variants with different temperature grades, such as LTC2383IMS-16 or LTC2383HMS-16. Cross-family comparisons should consider the LTC2380-16 for higher resolution needs or the LTC2382-16 for lower power requirements.
