LTC2370IDE-16#PBF

Analog To Digital Converters (ADC) Overview

The LTC2370IDE-16#PBF is a 16-bit, 2Msps successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices Inc. Operating from a single 2.5V supply, it features a pseudo-differential unipolar input range of 0V to VREF, where VREF ranges from 2.5V to 5.1V. The device dissipates 19mW at maximum sampling rate and achieves ±0.85LSB integral nonlinearity with no missing codes at 16 bits. It delivers a typical signal-to-noise ratio of 94dB and supports SPI-compatible serial interfaces with logic voltages from 1.8V to 5V.

Analog To Digital Converters (ADC) Feature Summary

• 16-bit resolution with guaranteed no missing codes and ±0.85LSB maximum INL
• High-speed 2Msps throughput with zero cycle latency and internal oscillator
• Low power consumption of 19mW at 2Msps, scaling down to 19µW in power-down mode
• Flexible I/O interface supporting 1.8V, 2.5V, 3.3V, and 5V logic levels via OVDD

Analog To Digital Converters (ADC) Applications

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

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix #PBF indicates lead-free finish and tape and reel availability if required. Confirm the IDE suffix corresponds to the –40°C to 85°C operating temperature range and the 16-lead 4mm × 3mm DFN package. Ensure compatibility with system voltage requirements for VDD (2.5V) and OVDD (1.71V to 5.25V).

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit SAR ADC with low power dissipation and high speed is required. The IDE variant is suitable for industrial environments requiring operation down to –40°C. Ensure the application can provide a stable reference voltage between 2.5V and 5.1V and that the host interface logic matches the OVDD supply range.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2370-16 family of 16-bit SAR ADCs. Variants include CMS (0°C to 70°C), IMS (–40°C to 85°C MSOP), HMS (–40°C to 125°C MSOP), CDE (0°C to 70°C DFN), and IDE (–40°C to 85°C DFN). All share identical electrical specifications but differ in package type and operating temperature range.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same family include LTC2370IMS-16#PBF (MSOP package, same temp range) and LTC2370HMS-16#PBF (MSOP package, extended temp range). Cross-package substitution requires PCB layout changes due to differences between DFN and MSOP footprints.
