LTC2301IMS#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2301IMS#TRPBF is a single-channel, 12-bit successive approximation register (SAR) analog-to-digital converter (ADC) from Analog Devices. It features an I²C compatible serial interface and operates from a single 5V supply. The device includes an internal 2.5V reference and a fully differential sample-and-hold circuit. Key electrical parameters include a throughput rate of 14 ksps, a conversion time of 1.3μs, and a signal-to-noise ratio (SNR) of 73.5dB at 1kHz input. Power consumption is 1.5mW at 1ksps, with a sleep mode reducing dissipation to 35μW. It is housed in a 12-lead Plastic MSOP package and supports an operating temperature range of –40°C to 85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix #TRPBF indicates tape and reel packaging. Confirm the IMS suffix corresponds to the industrial temperature grade (-40°C to 85°C). Ensure compatibility with the 12-lead MSOP footprint during procurement planning.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring a single-ended or differential input with I²C connectivity. The LTC2301 offers one channel, whereas the LTC2305 provides two channels. Verify that the 5V supply voltage aligns with system power rails and that the 14 ksps throughput meets data acquisition requirements.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2301/LTC2305 family of low noise, low power 12-bit ADCs. The IMS variant specifically denotes the industrial temperature range and MSOP package. It is designed to replace older parallel or SPI-based ADCs where space and pin count are constrained.

Analog To Digital Converters (ADC) FAQ

What is the maximum sampling rate of the LTC2301?

The LTC2301 supports a maximum throughput rate of 14 ksps when performing successive reads.

How is the chip address configured?

The chip address is configured via the AD0 and AD1 pins, which can be set to LOW, HIGH, or floating states to select one of nine unique addresses plus a global synchronization address.

Can the input range be changed dynamically?

Yes, the input range can be programmed as unipolar or bipolar via the DIN word sent over the I²C interface.
