LTC2393CUK-16#PBF

Overview

The LTC2393CUK-16#PBF is a 16-bit, 1Msps 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 signal-to-noise ratio (SNR) of 94.2dB at a 20kHz input frequency with a maximum integral nonlinearity (INL) of ±2LSB. It includes an internal precision reference with a maximum temperature coefficient of ±20ppm/°C. Power consumption is 140mW at full throughput, supported by nap and sleep power-down modes. The component is housed in a 48-lead 7mm × 7mm plastic QFN package.

• 1Msps sampling rate with no pipeline delay or cycle latency
• Internal 4.096V reference with ±20ppm/°C max temperature coefficient
• Supports both parallel and serial digital interfaces

Applications

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

Procurement Notes

Verify the specific suffix #PBF indicates tube packaging for this part number. Confirm the C grade corresponds to the 0°C to 70°C operating temperature range. Ensure compatibility with the 48-lead QFN footprint during procurement planning.

Selection Notes

Select this model for applications requiring high dynamic range and low noise at moderate speeds. The internal reference simplifies design but external references may be needed for tighter accuracy requirements. Verify interface mode (parallel vs. serial) needs against system constraints.

Part Context

This component belongs to the LTC2393 family of SAR ADCs. The UK suffix denotes the 48-lead QFN package variant, distinguishing it from the LX LQFP package options available in the same series.
