LTC2306CDD#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2306CDD#TRPBF is a low noise, 500ksps, 2-channel, 12-bit successive approximation register (SAR) analog-to-digital converter. It features an SPI/MICROWIRE compatible serial interface and an internal conversion clock allowing SCK operation up to 40MHz. The device operates from a single 5V supply, drawing 2.8mA at 500ksps, with auto-shutdown reducing current to 14µA at 1ksps. Key performance metrics include a SINAD of 72.8dB, INL of ±0.3 LSB, DNL of ±0.25 LSB, and power dissipation of 14mW. It is housed in a 10-lead 3mm × 3mm DFN package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix #TRPBF indicates tape and reel packaging, distinct from the tube-packaged #PBF variant. Confirm the temperature grade 'C' corresponds to the 0°C to 70°C operating range. Ensure the specific lot date code meets project requirements as manufacturing dates vary by batch.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC2306 over the LTC2302 when two independent input channels are required. Verify that the external reference voltage range (0.1V to VDD) aligns with system requirements. Ensure the OVDD supply (2.7V to 5.25V) matches the digital logic levels of the host microcontroller or DSP.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC2302/LTC2306 family of low-power SAR ADCs. It shares software compatibility with the LTC2308 but differs in channel count and reference integration. The CDD suffix denotes the commercial temperature grade and DFN package type.
