LTC2301CDE#PBF

Analog To Digital Converters (ADC) Overview

The LTC2301CDE#PBF is a 12-bit successive approximation register (SAR) analog-to-digital converter (ADC) featuring an I²C compatible serial interface. It operates from a single 5V supply, drawing 300μA at a throughput rate of 1ksps and consuming 1.5mW. The device includes an internal 2.5V reference and a fully differential sample-and-hold circuit. Key electrical parameters include a 14ksps maximum sampling rate, a conversion time of 1.3μs, and a signal-to-noise ratio (SNR) of 73.5dB. It supports unipolar or bipolar input ranges via software selection and is housed in a 12-lead 3mm × 4mm plastic DFN package with an operating temperature range of 0°C to 70°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix #PBF indicates lead-free finish and tube packaging for this part number. Confirm the 'C' grade designation corresponds to the commercial temperature range of 0°C to 70°C. Ensure the DFN package variant matches the required PCB footprint, noting the exposed pad must be soldered to ground.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC2301CDE#PBF for single-channel applications requiring I²C connectivity. For dual-channel requirements, consider the LTC2305 family instead. Verify that the system voltage aligns with the specified 4.75V to 5.25V VDD range. Ensure the host microcontroller supports the required I²C timing specifications for reliable data transfer.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC2301/LTC2305 family of low noise, low power 12-bit ADCs. The 'CDE' suffix denotes the Commercial temperature grade (-0°C to 70°C) and the 12-lead 3mm × 4mm Plastic DFN package. The '#PBF' suffix specifies the lead-free finish and tube shipping method.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitutes within the same family include the LTC2301IDE#PBF for extended industrial temperature ranges (-40°C to 85°C) and the LTC2301HMS#PBF for automotive/high-temperature applications (-40°C to 125°C). Package variations such as MSOP are available but require pinout verification.
