THD: −105 dB at 10 kHz
The ADAQ7980/ADAQ7988 contain a high accuracy, low power,
Zero error: ±0.06 mV typical (unity gain)
16-bit SAR ADC, a low power, high bandwidth, high input
Zero error temperature drift: 1.3 μV/°C maximum
impedance ADC driver, a low power, stable reference buffer,
Low power dissipation
and an efficient power management block. Housed within a tiny,

APPLICATIONS
The ADAQ7980/ADAQ7988 integrate within a compact,
Automated test equipment (ATE)
integrated circuit (IC)-like form factor key components
Battery powered instrumentation
commonly used in data acquisition signal chain designs. The
Communications
μModule family transfers the design burden of component
Data acquisition
selection, optimization, and layout from designer to device,
Process control
shortening overall design time, system troubleshooting, and
Medical instruments
ultimately improving time to market.
GENERAL DESCRIPTION
The serial peripheral interface (SPI)-compatible serial interface features the ability to daisy-chain multiple devices on a single, 3- The ADAQ7980/ADAQ7988 are 16-bit analog-to-digital converter wire bus and provides an optional busy indicator. The user (ADC) μModule® data acquisition systems that integrate four interface is compatible with 1.8 V, 2.5 V, 3 V, or 5 V logic. common signal processing and conditioning blocks into a system in package (SiP) design that supports a variety of applications. Specified operation of these devices is from −55°C to +125°C. These devices contain the most critical passive components,
