LTC2328CMS-16#PBF

Analog To Digital Converters (ADC) Overview

The LTC2328CMS-16#PBF is a 16-bit successive approximation register (SAR) analog-to-digital converter with pseudo-differential inputs. It operates from a single 5V supply and supports true bipolar input ranges of ±6.25V, ±10.24V, or ±12.5V. The device achieves a maximum integral nonlinearity (INL) of ±1.5 LSB with guaranteed no missing codes at 16 bits. It delivers a typical signal-to-noise ratio (SNR) of 93.5 dB and total harmonic distortion (THD) of –111 dB at a 1Msps sampling rate. Power consumption is 50mW at full throughput, scaling down to 300μW in sleep mode.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific temperature grade for the application environment. The CMS suffix indicates the commercial range (0°C to 70°C). For industrial (-40°C to 85°C) or extended (-40°C to 125°C) temperatures, select the IMS or HMS variants respectively. Confirm package availability as MSOP-16.

Analog To Digital Converters (ADC) Selection Notes

Select based on required input voltage range and operating temperature. The internal reference buffer allows direct connection to the 2.048V REFIN pin for ±10.24V operation. For higher precision, an external reference can overdrive the REFIN pin. Ensure OVDD matches the host logic voltage (1.8V–5V) for proper SPI communication levels.
