1 General Description
The AS1543/44 is a 12-bit high-speed, low-power, 8/4channel, successive-approximation ADC that operates from a single 2.7 to 5.25V supply. The device features high throughput rates (1Msps) and a low-noise, widebandwidth track-and-hold amplifier that can handle input frequencies in excess of 1 MHz. The AS1543 features 8 single-ended or 4 fully differential analog inputs while the AS1544 offers 4 singleended or 2 fully differential analog inputs. Both include a channel sequencer to allow a programmed selection of channels to be converted sequentially.
