LTC2450IDC-1#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2450IDC-1#TRPBF is a low-power, ultra-tiny 16-bit delta-sigma analog-to-digital converter (ADC) designed for space-constrained applications. It operates on a single 2.7V to 5.5V supply and accepts a single-ended analog input voltage ranging from GND to VCC. The device communicates via an SPI interface and features an integrated oscillator requiring no external components. Key electrical specifications include a resolution of 16 bits with no missing codes, a maximum conversion time of 21ms, and a transition noise of 1.4μV RMS. Supply current is 350μA during conversion and reduces to less than 500nA in sleep mode.

Analog To Digital Converters (ADC) Feature Summary

• 16-bit resolution with no missing codes and 0.02LSB RMS noise
• Ultra-tiny 6-lead, 2mm × 2mm DFN package
• Single-ended rail-to-rail input range (GND to VCC)
• Integrated oscillator eliminates need for external clock components

Analog To Digital Converters (ADC) Applications

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

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix #TRPBF indicates tape and reel packaging containing 2500 pieces. Confirm the 'I' grade designation corresponds to the -40°C to 85°C operating temperature range. Ensure the DC package type matches the required 6-lead DFN footprint for PCB layout compatibility.

Analog To Digital Converters (ADC) Selection Notes

Select this component when 16-bit accuracy is required in minimal board space. The internal oscillator simplifies design by removing external clock sources. Verify that the single-ended input architecture meets system requirements, as differential inputs are not supported. Ensure the host microcontroller supports the 3-wire SPI interface timing constraints.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2450 family of ultra-tiny ADCs. The IDC-1 suffix denotes the industrial temperature grade (-40°C to 85°C), while the TRPBF suffix specifies tape and reel packaging with lead-free finish. It is functionally similar to the LTC2450 but optimized for specific single-ended applications within the same package constraint.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate other members of the LTC2450 family or comparable 16-bit delta-sigma ADCs based on package size and interface compatibility.
