Frequently Asked Questions
How many input channels does TLC2558IDWG4 support and what input configuration is used?
TLC2558IDWG4 provides 8 differential analog input channels, allowing common-mode noise rejection. The device accepts analog input voltages up to 5.5 V and is well-suited for precision multichannel sensor acquisition in industrial and measurement systems.
What is the maximum conversion time and resolution of TLC2558IDWG4?
TLC2558IDWG4 achieves a maximum conversion time of 2.5 µs with 12-bit resolution, yielding 4096 quantization levels. This combination supports sampling rates fast enough for real-time data logging and closed-loop control applications operating at several hundred kHz throughput.
In which package does TLC2558IDWG4 ship and what PCB footprint does it require?
TLC2558IDWG4 is packaged in a 20-pin SOIC (Small Outline IC) with a standard 1.27 mm pitch and body width of 7.5 mm, requiring roughly 200 mm² of board area. The surface-mount format simplifies automated assembly compared to through-hole alternatives.
When would TLC2558IDWG4 be preferred over an 8-bit ADC for a sensor interface design?
When the sensor signal spans a full 5 V range but must resolve changes smaller than 2 mV, TLC2558IDWG4's 12-bit resolution (LSB ≈ 1.34 mV at 5.5 V) is necessary. An 8-bit device would produce 21.5 mV per LSB, insufficient for precision pressure or temperature transducer readings requiring better than 0.5% accuracy.
