Part details & applications

The ADAQ4216 is a μModule^® precision data-acquisition (DAQ) signal chain solution that reduces the development cycle of a precision measurement system by transferring the signal-chain design challenge of component selection, optimization, and layout from the designer to the device. With a guaranteed maximum ±3ppm INL and no missing codes at 16 bits, the ADAQ4216 achieves unparalleled precision from −40°C to +105°C.

Using system-in-package (SIP) technology, the ADAQ4216 combines the common signal processing blocks required in a data-acquisition solution in a small footprint, 14mm × 9mm, 0.8mm pitch, 178-ball CSP_BGA package.

The ADAQ4216 integrates the following:

A low-noise, high-bandwidth programmable gain instrumentation amplifier (PGIA).
A second-order anti-aliasing filter.
A low-noise, low-distortion, high-bandwidth analog‐to‐digital converter (ADC) driver.
A high precision 16-bit, 2MSPS successive approximation register (SAR) ADC.
A 1.8V low dropout (LDO) regulator.
Performance critical passives.
