Description

The AS1538/AS1540 are single-supply, low-power, 12-bit data acquisition devices featuring a serial I²C interface
and an 8-channel (AS1538) or 4-channel (AS1540) multiplexer.

The analog-to-digital (A/D) converters features a sample-and-hold amplifier an internal asynchronous clock and an internal reference.

The combination of an I2C serial, 2-wire interface and micropower consumption makes the AS1538 and AS1540 ideal for applications requiring the A/D converter to be close to the input source in remote locations and for applications requiring isolation.

The device is available in a TSSOP-16 or TQFN 4x4 16-pin package.
