ADAS1127 64-Channel, 24-Bit Current-to-Digital ADC
The ADAS1127 is a 64-channel, current-to-digital, analog-to-digital converter (ADC). It contains 64 low power, low noise, low input current integrators, simultaneous sample-and-holds, and a high speed, high resolution ADCs with configurable sampling rate and resolutions up to 24 bits.
Applications
All converted channel results are output on a single LVDS self-clocked serial interface, which reduces external hardware.
An SPI-compatible serial interface allows configuration of the ADC using the SDI input. The SDO output allows the user to daisy-chain several ADCs on a single, 3-wire bus. The ADAS1127 uses the separate supply IOVDD to reduce the digital noise effect on the conversions.
The ADAS1127 is in a 10 mm × 10 mm, mini-BGA package.
