ADAQ23875BBCZ

Overview

The ADAQ23875BBCZ is a 16-bit, 15 MSPS µModule data acquisition solution from Analog Devices. It integrates a successive approximation register (SAR) ADC, a fully differential analog-to-digital converter driver (FDA), and a reference buffer within a 9 mm × 9 mm, 0.8 mm pitch, 100-ball CSP_BGA package. The device operates on a single 5 V supply with a typical power dissipation of 143 mW at maximum throughput. Key electrical specifications include an integral nonlinearity (INL) of ±0.6 LSB typical, a signal-to-noise ratio (SNR) of 89.5 dB at 1 kHz input frequency, and a total harmonic distortion (THD) of −115 dB at 1 kHz. It features a serial LVDS digital interface and supports an operating temperature range from −40°C to +85°C.
