TLV2543CN

Analog To Digital Converters (ADC) Overview

The TLV2543CN is a 12-bit successive approximation analog-to-digital converter (ADC) manufactured by Texas Instruments. It features an SPI-compatible serial interface and supports 11 single-ended analog input channels. The device operates on a single power supply ranging from 3 V to 3.6 V for both analog and digital domains, consuming approximately 3.3 mW of power. It achieves a sampling rate of 66 kS/s with differential nonlinearity and integral nonlinearity specified at +/- 1 LSB. The component is housed in a 20-pin PDIP package designed for through-hole mounting and functions within a commercial temperature range of 0°C to +70°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates an external reference input pin for flexible voltage referencing configurations
• Supports programmable power-down modes to reduce current consumption during idle periods
• Includes a built-in self-test mode for verifying internal circuit functionality

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel data acquisition
• Battery-powered instrumentation utilizing low-voltage operation
• Data logging devices with moderate speed requirements

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'CN' corresponds to the commercial temperature grade and PDIP-20 package configuration. Confirm that the external reference requirement aligns with system design constraints. Ensure compatibility with 3.3 V logic levels for the serial interface connections.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a low-power, 12-bit resolution ADC is required for single-supply applications. Compare against the TLC2543IN if wider operating temperatures or higher voltage supplies are necessary. Consider the TLV2543CDBR variant if surface-mount packaging is preferred over through-hole installation.

Analog To Digital Converters (ADC) Part Context

This part belongs to the TLV2543 series of low-power ADCs. It shares functional similarities with the TLC2543 family but is optimized for lower voltage operation. The CN suffix specifically denotes the commercial temperature range and plastic dual in-line package style used in standard PCB layouts.

Analog To Digital Converters (ADC) Replacement Considerations

The TLC2543IN serves as a pin-compatible alternative but requires a 4.5 V to 5.5 V supply. Verify voltage level compatibility before substitution.
