AS1541 A/D Converter IC

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.

Key Features

  • Single Supply: 2.7 to 5.25V
  • 8-Channel Multiplexer (AS1539)
  • 4-Channel Multiplexer (AS1541)
  • Sampling Rate: 50ksps
  • No Missing Codes
  • Internal Reference: 2.5V
  • High Speed I²C Interface at 3.4MHz
  • <1.5μA Full Shutdown Current
  • TSSOP-16 or TQFN 4x4 16-pin Package

Applications

The device is ideal for voltage-supply monitoring, isolated data acquisition, transducer interfaces, battery-operated systems, remote data acquisition or any other analog-to-digital conversion application.
