What are the key features of TLC3544IDWG4?
- 14-bit resolution with 0.0061% maximum linearity error enabling precision measurement in industrial sensor and instrumentation front-ends
- 4-channel simultaneous-capable analog input up to 4.07 V with 2.785 µs maximum conversion time supporting multi-sensor data acquisition
- SPI-compatible serial interface in a 20-pin SOIC package simplifies microcontroller integration with minimal external components
What is TLC3544IDWG4 used for?
TLC3544IDWG4 is used in industrial process-control instruments and precision data-acquisition cards where 4 sensor channels must be digitised at 14-bit resolution with conversion latencies under 3 µs. Its low linearity error of 0.0061% suits strain-gauge bridges, thermocouple signal chains, and pressure transducer front-ends where sub-millivolt accuracy is required across the signal range. The device also suits multi-channel vibration monitoring and motor-current sensing systems that sample up to 4 inputs sequentially using a shared SPI port.

Frequently Asked Questions
What resolution and conversion speed does TLC3544IDWG4 offer for industrial sensor data acquisition?
TLC3544IDWG4 provides 14-bit resolution with a maximum conversion time of 2.785 µs per channel, corresponding to a throughput of approximately 360 kSPS. The 14-bit depth yields 16,384 discrete output codes across an analog input range up to 4.07 V, resolving voltage steps as small as 250 µV for precision transducer signal chains.
How does TLC3544IDWG4's linearity error affect measurement accuracy in a strain-gauge bridge circuit?
With a maximum integral nonlinearity (INL) of 0.0061%, TLC3544IDWG4 introduces less than 1 LSB of linearity error at 14-bit resolution. In a 4 mV/V strain-gauge bridge excited at 5 V, this translates to a measurement error below 1.2 µV, which is well within the accuracy budget for load cells and structural health monitoring systems requiring sub-0.01% linearity.
How does the 4-channel input structure of TLC3544IDWG4 reduce BOM in a multi-sensor design?
TLC3544IDWG4 integrates 4 analog input channels with a multiplexed successive-approximation converter, replacing a single-channel ADC plus a 4:1 external multiplexer and its associated level-shifting components. This consolidation reduces BOM parts by at least 5–8 components and shrinks PCB area by eliminating a separate 4:1 mux footprint alongside the 20-pin SOIC ADC.
What SPI bus configuration is required to interface TLC3544IDWG4 with a microcontroller?
TLC3544IDWG4 uses a standard 4-wire SPI interface (SCLK, MOSI/DIN, MISO/DOUT, CS) operating in SPI Mode 0 or Mode 1 at clock rates up to 10 MHz. The 14-bit result is clocked out MSB-first in a 16-bit frame, so a single microcontroller SPI peripheral with 16-bit word mode can read all 4 channels sequentially in approximately 14 µs total at 10 MHz, without any glue logic.
