TLV1504IPWR

Analog To Digital Converters (ADC) Overview

The TLV1504IPWR is a 10-bit, 200-kSPS analog-to-digital converter (ADC) manufactured by Texas Instruments. It operates from a single 2.7-V to 5.5-V supply and features an on-chip analog multiplexer with four input channels. The device includes a built-in reference, conversion clock, and an 8-word FIFO buffer. It supports SPI-compatible serial interfaces with SCLK up to 20 MHz. Differential and integral nonlinearity errors are ±1 LSB, with a signal-to-noise and distortion ratio of 59 dB at 12 kHz. Operating current is 1.0 mA at 3.3 V. It is housed in a 16-pin TSSOP package.

Analog To Digital Converters (ADC) Feature Summary

• Built-in reference voltage and conversion clock for simplified system design
• Integrated 8-word FIFO buffer to reduce host processor overhead
• Hardware-controlled and programmable sampling period via CSTART pin
• Programmable auto-channel sweep capability for multi-point monitoring

Analog To Digital Converters (ADC) Applications

• Data acquisition systems requiring low power consumption
• Industrial process control applications with multiple sensor inputs
• Battery-powered instrumentation utilizing wide-range single-supply operation
• Embedded systems interfacing with DSPs or microcontrollers via SPI

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix IPWR corresponds to the industrial temperature range (-40°C to 85°C) and the 16-pin TSSOP package configuration. Confirm that the component matches the SLAS251A datasheet revision. Ensure compatibility with the required supply voltage range of 2.7 V to 5.5 V for the target application environment.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 10-bit resolution and 200 kSPS throughput are sufficient for the application. Consider the internal reference and FIFO features if minimizing external components is a priority. Evaluate the 4-channel multiplexing capability against the total number of analog signals required. Verify that the serial interface timing aligns with the host processor's maximum SCLK speed.

Analog To Digital Converters (ADC) Part Context

The TLV1504 belongs to a family of high-performance, low-power CMOS ADCs that also includes the TLV1508. Both devices share similar architectural features but differ in the number of analog input channels. The TLV1504 specifically provides four multiplexed inputs, whereas the TLV1508 offers eight. Pin-compatible 12-bit upgrades such as the TLV2544 and TLV2548 are available within the same product line.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives include the TLV1508 for applications requiring additional analog input channels. For higher resolution requirements, consider the TLV2544 or TLV2548, which offer 12-bit performance while maintaining similar interface characteristics.
