LTC2453CDDB#TRMPBF

Analog To Digital Converters (ADC) Overview

The LTC2453CDDB#TRMPBF is an ultra-tiny, fully differential, 16-bit analog-to-digital converter (ADC) from Analog Devices. It operates on a single 2.7V to 5.5V supply and communicates via a 2-wire I²C interface. The device features an integrated oscillator, eliminating the need for external components, and utilizes a delta-sigma modulator core with no latency for multiplexed applications. Key electrical specifications include a resolution of 16 bits with no missing codes, a maximum offset error of 2 LSB, and a full-scale error of 4 LSB. The ADC samples at 60 conversions per second, drawing 800µA during conversion and reducing power consumption to less than 0.2µA in sleep mode.

Analog To Digital Converters (ADC) Feature Summary

• 16-bit resolution with no missing codes, 2LSB offset error, and 4LSB full-scale error
• Fully differential input range of ±VCC with proprietary sampling scheme reducing average input current to 50nA
• Single-cycle operation with automatic shutdown to sleep mode (<0.2µA) after each conversion
• Integrated internal oscillator requiring no external components

Analog To Digital Converters (ADC) Applications

• System monitoring
• Environmental monitoring
• Direct temperature measurements
• Industrial process control
• Data acquisition

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix #TRMPBF confirms the Mini Tape and Reel packaging containing 500 pieces. Confirm the C grade designation indicates an operating temperature range of 0°C to 70°C. Ensure the DDB package type corresponds to the 8-lead, 3mm × 2mm plastic DFN form factor required for the design.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a fully differential input is required with a wide common-mode range extending to VCC. The low average input sampling current allows direct interfacing with high-impedance sources or simple RC filters without significant error. Verify that the I²C slave address 0010100 fits the bus topology and that the 60 SPS sample rate meets application timing requirements.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2453 family of ultra-tiny differential ADCs. The CDDB suffix identifies the commercial temperature grade (0°C to 70°C) and the DDB 8-lead DFN package. Other variants include the IDDB for industrial temperature ranges (-40°C to 85°C) and the TS8 package options.

Analog To Digital Converters (ADC) Replacement Considerations

Public confirmed substitutes include the LTC2453IDDB#TRMPBF for industrial temperature grades and the LTC2453CTS8#TRMPBF for TSOT-23 packaging. Cross-model compatibility within the LTC2453 series maintains pinout and functional equivalence.
