TLV1544CPWG4

Analog To Digital Converters (ADC) Overview

The TLV1544CPWG4 is a low-voltage, 10-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It utilizes a CMOS switched-capacitor successive-approximation architecture and features an on-chip 11-channel multiplexer providing four selectable analog input channels. The device operates with a wide single-supply voltage range of 2.7 V to 5.5 V and supports serial interfaces compatible with SPI, QSPI, and TMS320 DSPs. Key electrical parameters include a maximum I/O clock frequency of 10 MHz at 4.5 V supply, conversion times of 7 μs for fast mode and 15 μs for slow mode, and a typical power-down current of 1 μA.

Analog To Digital Converters (ADC) Feature Summary

• Built-in 11-channel multiplexer allowing selection among four external analog inputs or three internal self-test voltages
• Flexible serial interface supporting microprocessor SPI/QSPI modes and dedicated TMS320 DSP frame synchronization
• Programmable power-down state and dual conversion rates to optimize power consumption for battery-operated applications
• Asynchronous start capability via CSTART pin to extend sampling time for high source impedance signals

Analog To Digital Converters (ADC) Applications

• Portable instrumentation requiring low-power data acquisition
• Industrial process control systems utilizing TMS320 digital signal processors
• Battery-powered measurement devices needing programmable power management
• Data acquisition modules interfacing with general-purpose microcontrollers via SPI

Analog To Digital Converters (ADC) Procurement Notes

Verify the component marking against the official datasheet specifications to confirm authenticity. Ensure the ordering suffix matches the required temperature grade and package variant. Confirm RoHS compliance status through manufacturer documentation prior to integration into production designs.

Analog To Digital Converters (ADC) Selection Notes

Select this model when four analog input channels are sufficient for the application design. Choose between the 'C' industrial grade or other variants based on specific operating temperature requirements. Consider the extended sampling feature if the connected sensor source impedance exceeds standard limits.

Analog To Digital Converters (ADC) Part Context

This component belongs to the TLV154x family of low-voltage ADCs. The TLV1544 variant specifically provides four analog inputs, whereas the TLV1548 offers eight. Both share identical core conversion architectures and serial interface protocols, differing primarily in channel count and physical pinout configurations.

Analog To Digital Converters (ADC) Replacement Considerations

Direct functional replacements within the same series include the TLV1548CPW for applications requiring additional input channels. Verify pin compatibility and software register definitions when substituting between different package types such as D, DB, or PW.
