TLV2548IPW

Analog To Digital Converters (ADC) Overview

The TLV2548IPW is a high-performance, low-power, 12-bit CMOS analog-to-digital converter (ADC) manufactured by Texas Instruments. It operates from a single power supply ranging from 3.0 V to 5.5 V and supports up to 200 kSPS throughput with a typical conversion time of 3.86 µs. The device features an internal analog multiplexer selectable for four or eight channels, along with built-in reference voltage, conversion clock, and an 8-level FIFO buffer. It interfaces via a standard SPI-compatible serial port supporting SCLK frequencies up to 20 MHz. Designed for extended reliability, it functions within a military-grade temperature range of –55°C to +125°C and is housed in a 20-pin TSSOP package.

Analog To Digital Converters (ADC) Feature Summary

• Integrated analog multiplexer allows selection between four or eight input channels plus internal self-test voltages.
• Built-in reference voltage, conversion clock, and 8-level FIFO buffer reduce external component requirements.
• Supports software, hardware, and automatic shutdown modes to minimize power consumption during idle periods.
• Compatible with DSP systems using frame sync signals and offers programmable sampling periods.

Analog To Digital Converters (ADC) Applications

• Defense and aerospace data acquisition systems
• Medical instrumentation requiring high reliability
• Industrial control systems with harsh environmental conditions

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'IPW' corresponds to the 20-pin TSSOP package and commercial/extended temperature grade when sourcing. Confirm that the 'EP' designation found in some documentation refers to enhanced product stability or traceability standards if required for your specific supply chain audit. Ensure compatibility with existing SPI bus configurations regarding clock polarity and phase settings.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution and 200 kSPS speed are sufficient for the application's signal bandwidth. Consider the internal multiplexer and FIFO capabilities if channel switching overhead needs to be minimized. Evaluate the power consumption profiles across different supply voltages and shutdown modes against system battery life requirements. Verify that the 20-pin TSSOP footprint fits the PCB layout constraints.

Analog To Digital Converters (ADC) Part Context

The TLV2548 belongs to Texas Instruments' broader family of low-power serial ADCs, sharing architectural similarities with parts like the TLV2544 and TLV2541. These devices typically offer comparable performance metrics but may vary in channel count or pinout configuration. The TLV2548 specifically addresses applications needing multiple analog inputs with integrated buffering and robust operation in extreme temperatures.

Analog To Digital Converters (ADC) Replacement Considerations

The TLV2544 is a direct functional substitute within the same series, offering identical specifications and pinouts. Other compatible alternatives include the TLV2541 for single-channel applications or the TLV1504 for 10-bit resolution requirements. Always verify package compatibility and temperature ranges before substitution.
