LTC2377IDE-20#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2377IDE-20#TRPBF is a 20-bit, 500ksps low power SAR ADC from Analog Devices. Operating from a 2.5V supply with a VREF range of 2.5V to 5.1V, it consumes 10.5mW at full speed. Key electrical parameters include ±2ppm maximum INL, guaranteed 20-bit no missing codes, and 104dB SNR. It features an SPI-compatible serial interface supporting 1.8V to 5V logic, digital gain compression (DGC), and an internal oscillator. The device is housed in a 16-lead DFN package and operates within the industrial temperature range of –40°C to 85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix #TRPBF indicates tape and reel packaging. Confirm the IDE designation corresponds to the industrial temperature grade (-40°C to 85°C) and the DE package type (16-Lead DFN). Ensure compatibility with the required 2.5V analog supply and 1.8V-5V I/O voltage levels during procurement planning.

Analog To Digital Converters (ADC) Selection Notes

Select this component when 20-bit resolution and high linearity are critical. The Digital Gain Compression feature allows driving the ADC from a single positive supply by mapping the input range to 10%-90% of VREF. Ensure the application supports a 2.5V analog supply and that the host interface logic voltage falls within the 1.8V to 5.25V OVDD range.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2377 family of low noise, low power SAR ADCs. The 'I' suffix denotes the industrial temperature range variant, while 'DE' specifies the 4mm x 3mm plastic DFN package. The '#TRPBF' suffix identifies the specific tape and reel packaging configuration for automated assembly.

Analog To Digital Converters (ADC) Replacement Considerations

For pin-compatible replacements within the same family, consider the LTC2377CDE-20#TRPBF for commercial temperature range applications. Other resolutions such as the LTC2377IDE-18 or LTC2377IDE-16 offer similar interfaces but with different bit depths and performance characteristics.
