LTC2306CDD#PBF

Analog To Digital Converters (ADC) Overview

The LTC2306CDD#PBF is a low noise, 500ksps, 12-bit Analog-to-Digital Converter (ADC) featuring two independent input channels. It utilizes a Successive Approximation Register (SAR) architecture with an internal conversion clock and an SPI/MICROWIRE compatible serial interface. The device operates from a single 5V supply, drawing 2.8mA at maximum sampling rates, while an auto-shutdown feature reduces current to 14µA at 1ksps. Key performance metrics include a Signal-to-Noise and Distortion Ratio (SINAD) of 72.8dB, Total Harmonic Distortion (THD) of -88dB, and Spurious Free Dynamic Range (SFDR) of 89dB. It is housed in a compact 10-pin 3mm × 3mm DFN package.

Analog To Digital Converters (ADC) Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific ordering suffix matches the required temperature grade and packaging format. Check for RoHS compliance documentation as indicated in official specifications. Ensure the part number corresponds to the C-grade variant for the specified operating temperature range.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC2306CDD#PBF when dual-channel acquisition is required within a 12-bit resolution constraint. This model supports unipolar or bipolar input ranges via software configuration. Ensure the external reference voltage falls within the 0.1V to VDD range. Verify that the system power budget accommodates 14mW at full speed or utilizes the sleep mode for lower average power consumption.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC2302/LTC2306 family of low-power SAR ADCs. The LTC2306 specifically provides two analog input channels, whereas the LTC2302 offers a single differential channel. Both share identical electrical characteristics, serial interfaces, and pinouts, differing primarily in the internal multiplexer configuration for channel selection.
