AD7634BCPZ Description

Short technical summary and product information.

The AD7634BCPZ is an 18-bit successive approximation register (SAR) analog-to-digital converter (ADC) from Analog Devices. It achieves a maximum throughput of 670 kSPS in warp mode, with typical power dissipation of 180 mW. The device features a programmable input voltage range supporting 5 V (10 V p-p), +10 V (20 V p-p), ±5 V (20 V p-p), and ±10 V (40 V p-p) configurations, selectable via pins or SPI.

 

Key electrical specifications include a typical signal-to-noise ratio (SNR) of 101 dB at 2 kHz, total harmonic distortion (THD) of -112 dB, and an integral nonlinearity (INL) of ±1.5 LSB typical. The ADC incorporates a 5 V internal reference with a typical drift of 3 ppm/°C. It operates from a single 5 V supply and is specified over the -40°C to +85°C temperature range.

 

The AD7634BCPZ is housed in a 48-lead LFCSP (7 mm x 7 mm) package for surface mount assembly. It provides parallel (18-/16-/8-bit) and serial (SPI, DSP) data interfaces. The SAR architecture eliminates pipeline delay, making it suitable for high dynamic data acquisition applications such as CT scanners, spectrum analysis, and instrumentation.
