LTC2391CUK-16#PBF

Overview

The LTC2391CUK-16#PBF is a 16-bit, 250ksps successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices Inc. It operates from a single 5V supply and features a ±4.096V fully differential input range. The device achieves a typical SNR of 94dB at a 20kHz input frequency and guarantees 16-bit no missing codes with a maximum INL of ±2LSB. Power consumption is 95mW at full throughput, supported by nap and sleep power-down modes. It integrates a precision internal reference with a maximum temperature coefficient of ±20ppm/°C.

Feature Summary

16-bit resolution with guaranteed no missing codes and ±2LSB max INL
250ksps throughput rate with no pipeline delay or cycle latency
Internal precision reference offering 4.096V output with ±20ppm/°C max tempco
Supports both parallel and serial digital interfaces with 1.8V to 5V I/O voltages

Applications

Medical Imaging
High Speed Data Acquisition
Industrial Process Control
Instrumentation
Automated Test Equipment (ATE)

Procurement Notes

Verify the specific ordering suffix for packaging requirements. The #PBF designation indicates lead-free finish and RoHS compliance. Confirm that the C-grade variant meets the required operating temperature range of 0°C to 70°C for the intended application environment before procurement.

Selection Notes

Select this component when a low-noise, high-dynamic-range ADC is required for single-supply 5V systems. The internal oscillator simplifies external timing design. Ensure the input signal bandwidth does not exceed the 50MHz -3dB input bandwidth and that the source impedance is compatible with the acquisition time constraints for 16-bit accuracy.

Part Context

This part belongs to the LTC2391-16 series, which includes variants with different temperature grades and package options. The CUK-16 suffix specifically denotes the commercial temperature grade (0°C to 70°C) housed in a 48-lead 7mm × 7mm plastic QFN package. Other series members include industrial and extended temperature versions available in LQFP packages.
