AS1543 - 8/4-Channel 1 Msps 12-Bit ADC with Sequencer

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.

Key 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. The conversion time is determined by the SCLK frequency (also used as the master clock to control the c.
