LTC2348CLX-18

Analog To Digital Converters (ADC) Overview

The LTC2348CLX-18 is an octal, 18-bit Successive Approximation Register (SAR) Analog-to-Digital Converter (ADC) from Analog Devices. It operates at a sampling rate of 200ksps with differential inputs and supports a wide input common-mode range. The device features SoftSpan technology, allowing configurable full-scale input ranges including ±10.24V. It utilizes a single 5V analog supply and includes an internal oscillator for timing. Key performance metrics include a Signal-to-Noise Ratio (SNR) of 96.4dB and a Full Power Bandwidth (FPBW) of 6MHz. The component is housed in a 48-lead LQFP package.

Analog To Digital Converters (ADC) Part Context

The LTC2348CLX-18 belongs to the LTC2348 family of octal SAR ADCs. This series provides multiple resolution options (16-bit and 18-bit) and sampling rates (200ksps and 1Msps). The 'CLX' suffix indicates the commercial temperature grade (-40°C to +85°C) and tape-and-reel packaging format. It serves as a high-density solution for applications requiring simultaneous multi-channel conversion without external multiplexers.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same family include the LTC2348-16 (16-bit resolution) or the LTC2348-18-1M (1Msps speed variant). Verify that the required sampling rate and resolution meet system specifications when substituting.
