LTC2323IUFD-12#PBF

Analog To Digital Converters (ADC) Overview

The LTC2323IUFD-12#PBF is a dual-channel, 12-bit + sign successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices Inc. It operates at a throughput rate of 5 Msps per channel with one-cycle latency. The device features differential inputs with a wide common mode range and an internal low-drift reference. Key electrical specifications include ±0.5 LSB typical integral nonlinearity, 73 dB typical signal-to-noise ratio at 2 MHz input frequency, and –85 dB total harmonic distortion. Power consumption is 38 mW per channel under typical conditions, supporting single 3.3 V or 5 V supplies.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IUFD-12#PBF against official Analog Devices documentation to confirm industrial temperature range (-40°C to 85°C) and lead-free packaging status. Ensure compatibility with host interface voltage levels (OVDD 1.71 V to 2.5 V) before integration. Cross-reference pin configurations for QFN-28 packages to prevent layout errors.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel high-speed conversion with wide dynamic range is required. The 12-bit + sign format allows digitization of over- and underrange conditions, beneficial for control loop applications. Consider the internal reference stability if external precision references are not available. Verify that the 5 Msps throughput meets system bandwidth requirements.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2323 family of dual SAR ADCs. Variants within the series differ primarily in resolution (12-bit, 14-bit, 16-bit) and sampling speed (2 Msps, 5 Msps). The 'I' suffix denotes the industrial temperature grade, while 'H' indicates extended temperature operation. All variants share similar pinouts and interface protocols.
