LTC2305HMS#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2305HMS#TRPBF is a dual-channel, 12-bit successive approximation register (SAR) analog-to-digital converter with an I²C compatible serial interface. It operates from a single 5V supply and features an internal 2.5V reference. The device supports a throughput rate of 14ksps with a conversion time of 1.3μs. Key electrical parameters include a signal-to-noise ratio of 73.5dB, integral nonlinearity of ±0.4 LSB, and differential nonlinearity of ±0.3 LSB. Power consumption is 1.5mW at 1ksps, dropping to 35μW in sleep mode. It is housed in a 12-lead plastic MSOP package and rated for operation from –40°C to 125°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the 'H' suffix indicates the extended temperature range (-40°C to 125°C). Confirm the '#TRPBF' suffix denotes tape and reel packaging with lead-free finish. Check current availability status as distribution may vary.

Analog To Digital Converters (ADC) Selection Notes

Select this part for applications requiring two independent analog inputs with minimal external components. The internal reference eliminates the need for external voltage references. Ensure the I²C bus speed does not exceed 400kHz. Consider the 14ksps maximum sampling rate when designing filter networks.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC2301/LTC2305 family of low-power, 12-bit ADCs. The LTC2305 specifically provides two input channels, whereas the LTC2301 offers a single channel with configurable polarity. Both share the same interface and core architecture.
