AS1541
I²C Interfaced, 10-bit, 4-Channel, 50ksps ADC, TQFN 4x4 16-pin
Description
The AS1539/AS1541 are single-supply, low-power, 10-bit data acquisition devices featuring a serial I²C interface and an 8-channel (AS1539) or 4-channel (AS1541) 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 AS1539 and AS1541 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.
