8-Bit, 40 KSPS ADC Serial Out, Low Power, Compatible To TLC540/545/1540, Single Ch.

The TLC548 and TLC549 are CMOS Analog-to-digital converter (ADC) integrated circuits built around an 8-bit switched-capacitor successive-approximation ADC These devices are designed for serial Interface with a Microprocessor or peripheral through a 3-state data output and an Analog input. The TLC548 and TLC549 use only the input/output Clock (I/O CLOCK) input along with the chip select (CS) input for data control. The maximum I/O Clock input frequency of the TLC548 is 2.048 MHz, and the I/O Clock input frequency of the TLC549 is specified up to 1.1 MHz.
Operation of the TLC548 and the TLC549 is very similar to that of the more complex TLC540 and TLC541 devices; however, the TLC548 and TLC549 provide an on-chip system Clock that operates typically at 4 MHz and requires no external components. The on-chip system Clock allows internal device operation to proceed independently of serial input/output data Timing and permits manipulation of the TLC548 and TLC549 as desired for a wide range of software and hardware requirements. The I/O Clock together with the internal system Clock allow high-speed data transfer and conversion rates of 45 500 conversions per second for the TLC548 and 40 000 conversions per second for the TLC549.
Additional TLC548 and TLC549 features include versatile control Logic an on-chip sample-and-hold circuit that CAN operate automatically or under Microprocessor control, and a high-speed converter with differential high-impedance reference voltage inputs that ease ratiometric conversion, scaling, and circuit isolation from Logic and supply noises. Design of the totally switched-capacitor successive-approximation converter circuit allows conversion with a maximum total error of 0.5 least significant bit (LSB) in less than 17 us.
The TLC548C and TLC549C are characterized for operation from 0C to 70C. The TLC548I and TLC549I are characterized for operation from -40C to 85C.
