LTC2450IDC#TRMPBF

Analog To Digital Converters (ADC) Overview

The LTC2450IDC#TRMPBF is a 16-bit delta-sigma analog-to-digital converter (ADC) from Analog Devices, designed for ultra-low power and precision applications. It operates on a single supply voltage ranging from 2.7V to 5.5V, utilizing the supply rail as the internal reference. The device features a single-ended input range extending from GND to VCC and communicates via a standard 3-wire SPI interface. Key electrical specifications include a maximum conversion time of 42ms, resulting in up to 30 conversions per second. The ADC exhibits an integral nonlinearity of ±2 LSB with no missing codes, offset error of ±2 LSB, and full-scale error of ±4 LSB. It incorporates continuous internal calibration algorithms to ensure accuracy across temperature variations.

Analog To Digital Converters (ADC) Feature Summary

• 16-bit resolution with 2 LSB INL, no missing codes, and continuous internal offset/full-scale calibration.
• Ultra-tiny 6-lead 2mm × 2mm DFN package with integrated oscillator requiring no external components.
• Low power consumption: 350µA during conversion and less than 200nA in sleep mode.
• Single-ended rail-to-rail input range (GND to VCC) with proprietary sampling scheme reducing average input current to 50nA.

Analog To Digital Converters (ADC) Applications

• System monitoring
• Environmental monitoring
• Direct temperature measurements
• Instrumentation
• Industrial process control

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix #TRMPBF indicates a tape and reel packaging format with a minimum quantity of 500 pieces. Confirm the 'I' grade designation corresponds to the industrial temperature range of -40°C to +85°C. Ensure compatibility with the 6-lead DFN footprint and exposed pad grounding requirements during assembly.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high accuracy is required in space-constrained designs. The 16-bit resolution and low noise make it suitable for sensor interfaces where drift must be minimized. Consider the 33.3ms typical conversion time; if higher throughput is needed, this device may not meet speed requirements. The use of VCC as the reference simplifies design but requires a stable supply rail.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2450 family of ultra-tiny 16-bit ADCs. The 'I' suffix denotes the industrial temperature grade (-40°C to +85°C), distinguishing it from the 'C' grade commercial version (0°C to +70°C). The '#TRMPBF' suffix specifies the lead-free tape and reel packaging configuration.
