What are the key features of TLC2578IPWG4?

  • 8-channel 12-bit SAR ADC with ±10 V bipolar input range and 2.015 µs maximum conversion time for fast multi-channel scanning
  • 0.012% maximum linearity error ensures precise voltage measurement across the full -10 V to 10 V input span without calibration
  • 24-pin TSSOP package with RoHS-compliant green plastic molding suitable for compact industrial and instrumentation PCBs

What is TLC2578IPWG4 used for?

TLC2578IPWG4 is used in industrial data acquisition systems, process control panels, and test-and-measurement equipment that need to digitize 8 independent ±10 V analog sensor signals simultaneously. Its 12-bit resolution and sub-2 µs conversion speed make it well suited for PLC analog input cards and motor drive feedback channels where fast, accurate voltage sampling is essential. The device also targets precision weigh scales, pressure transmitters, and temperature monitoring systems that benefit from its low linearity error.

Frequently Asked Questions

How many input channels does TLC2578IPWG4 provide, and what is their voltage range?

TLC2578IPWG4 offers 8 analog input channels each accepting signals from -10 V to 10 V bipolar, covering a full 20 V span. This bipolar ±10 V range directly interfaces with standard industrial 4-20 mA transmitters and voltage-output sensors without external level-shifting or signal conditioning.

What conversion speed does TLC2578IPWG4 achieve, and why does that matter for multi-channel scanning?

TLC2578IPWG4 completes one 12-bit conversion in a maximum of 2.015 µs, allowing all 8 channels to be scanned in under 20 µs. This scan rate comfortably exceeds the bandwidth requirements of industrial process variables changing at tens of hertz, supporting real-time multi-loop control in PLCs and data acquisition boards.

What resolution and linearity does TLC2578IPWG4 offer compared to a basic 10-bit ADC?

TLC2578IPWG4 delivers 12-bit resolution with a maximum linearity error of 0.012%, or roughly 0.5 LSB at full scale. A typical 10-bit ADC provides 4x coarser steps and often higher linearity error, making TLC2578IPWG4 the better choice for precision weighing, pressure, and temperature measurements requiring sub-millivolt accuracy.

Which package does TLC2578IPWG4 use, and how does it fit on a data acquisition card?

TLC2578IPWG4 is housed in a 24-pin TSSOP package with a 0.65 mm pin pitch and body width of 4.4 mm, far smaller than a 24-pin DIP at 31.8 mm body length. This compact footprint makes it practical to mount 2 or more TLC2578 devices side by side on a standard 16-channel industrial analog input card.
