The recommended operating voltage range for TLC277IDG4 is 4.5V to 16V, although it can operate up to 18V with reduced performance.
To ensure proper power-up and initialization, apply a power-on reset (POR) signal to the VCC pin, and then wait for the internal voltage regulator to stabilize before applying a clock signal to the CLK pin.
The maximum clock frequency supported by TLC277IDG4 is 4 MHz, although it can operate at higher frequencies with reduced performance and increased power consumption.
The TLC277IDG4 can be configured for 8-bit or 10-bit ADC resolution by setting the appropriate bits in the control register. For 8-bit resolution, set the RES bit to 0, and for 10-bit resolution, set the RES bit to 1.
The conversion time for the TLC277IDG4 ADC is approximately 20 μs for 8-bit resolution and 40 μs for 10-bit resolution, assuming a clock frequency of 4 MHz.
