LTC2306IDD#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2306IDD#TRPBF is a low noise, 500ksps, 2-channel, 12-bit Analog-to-Digital Converter (ADC) from Analog Devices. It features an SPI/MICROWIRE compatible serial interface and a fully differential sample-and-hold circuit to reduce common mode noise. The device operates from a single 5V supply, drawing 2.8mA at 500ksps, with auto-shutdown reducing current to 14µA at 1ksps. Key electrical parameters include a SINAD of 72.8dB, INL of ±0.3 LSB, DNL of ±0.25 LSB, and SFDR of 89dB. 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. Confirm the IDD grade specifies the -40°C to 85°C operating temperature range. Ensure the source document matches the manufacturer's official datasheet for the LTC2306 family to validate pinout and electrical specifications.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC2306 over the LTC2302 when two independent analog input channels are required. The device supports both unipolar and bipolar input ranges via software selection. Ensure the external reference voltage is within the 0.1V to VDD range and that the OVDD supply is between 2.7V and 5.25V for proper digital interface operation.

Analog To Digital Converters (ADC) Part Context

The LTC2306 is part of the LTC2302/LTC2306 family of low noise SAR ADCs. It is software compatible with the LTC2308, which includes an internal reference. The IDD variant denotes the industrial temperature grade (-40°C to 85°C), while the CDD variant covers the commercial range (0°C to 70°C). Both share identical electrical characteristics and pinouts.
