AS1539/AS1541 Data Sheet 8/4-Channel, 10-Bit I²C Analog-to-Digital Converter 1 General Description 2 Key Features The AS1539/AS1541 are single-supply, low-power, Single Supply: 2.7 to 5.25V 10-bit data acquisition devices featuring a serial I²C interface and an 8-channel (AS1539) or 4-channel 8-Channel Multiplexer (AS1539) (AS1541) multiplexer. The analog-to-digital (A/D) converters features a sam- 4-Channel Multiplexer (AS1541) ple-and-hold amplifier an internal asynchronous clock and an internal reference. Sampling Rate: 50kSPS 2 The combination of an I C serial, 2-wire interface and No Missing Codes micropower consumption makes the AS1539 and AS1541 ideal for applications requiring the A/D con- Internal Reference: 2.5V verter to be close to the input source in remote locations and for applications requiring isolation. 2 High Speed I C Interface at 3.4MHz The device is available in a TSSOP-16 or TQFN 4x4 16- pin package. 1.5µA Full Shutdown Current TSSOP-16 or TQFN 4x4 16-pin Package
