AD677JRZ

The AD677JRZ is a 16-bit successive approximation register (SAR) analog-to-digital converter (ADC) from Analog Devices Inc. It features a 100 kSPS sampling rate and a single-ended input architecture. The converter uses an SPI data interface and requires an external voltage reference. The digital supply operates at 5V, while the analog supply is ±12V. The device includes an on-chip sample-and-hold function and autocalibration to ensure excellent DC performance, with integral nonlinearity (INL) of ±1 LSB and differential nonlinearity (DNL) of ±1 LSB (no missing codes). AC performance includes a signal-to-noise ratio (SNR) of 92 dB and total harmonic distortion (THD) of -99 dB. The full power bandwidth is 1 MHz. The input voltage range is ±5 V to ±10 V (relative to VREF). Typical power dissipation is 450 mW at VREF = 10V and 360 mW at VREF = 5V. The device is housed in a 28-SOIC (0.295", 7.50mm Width) package and is surface mountable. It operates over a temperature range of 0°C to 70°C. The AD677JRZ is suitable for applications requiring high precision and speed, such as industrial process control, medical instrumentation, and data acquisition systems.
