                      Product Overview

                      AD7634 is an 18-bit charge redistribution successive approximation register (SAR), architecture analog to digital converter (ADC) fabricated on Analog Devices, Inc.’s iCMOS high voltage process. The device is configured through hardware or via a dedicated write-only serial configuration port for input range and operating mode. The AD7634 contains a high speed 18-bit sampling ADC, an internal conversion clock, an internal reference (and buffer), error correction circuits and both serial and parallel system interface ports. The AD7634 features four different analog input ranges and three different sampling modes. Typical applications include CT scanners, high dynamic data acquisition, σ-δ replacement, spectrum analysis, medical instruments, instrumentation and process controls.

                      • Multiple pins/software-programmable input: 5V (10Vp-p), +10V (20V p-p), ±5V (20Vp-p), ±10V (40Vp-p)
                      • Pins or serial SPI-compatible input ranges/mode selection and no pipeline delay (SAR architecture)
                      • Throughput: 670KSPS (warp mode), 570KSPS (normal mode) and 450KSPS (impulse mode)
                      • 18bit resolution with no missing codes and INL: ±1.5LSB typ ±2.5LSB max (±9.5ppm of FSR)
                      • Dynamic range: 102.5dB, SNR: 101dB at 2KHz and THD: -112dB at 2KHz
                      • 5V internal reference: typical drift ±3ppm/°C; TEMP output
                      • Parallel (18-/16-/8-bit bus) and serial 5 V/3.3 V interface
                      • SPI-/QSPI™-/MICROWIRE™-/DSP-compatible
                      • Power dissipation: 180mW at 670KSPS( warp), 28mW at 100KSPS (impulse), 10mW at 1KSPS impulse mode
                      • 48 lead LQFP package, operating temperature range from -40 to 85°C
