AD7768 8-Channel, 24-Bit, simultaneous sampling ADC

Analog Devices' AD7768 24-Bit ADC allows designer engineers to trade off input bandwidth, output data rate, and power dissipation. Using one of the three power modes "" fast mode (256kSPS maximum), median mode (128kSPS maximum) and eco mode (32kSPS maximum) - designers can optimise their designs for noise targets and power consumption. In addition, the AD7768 offers extensive digital filtering capabilities, such as a wideband, low +/-0.005dB pass-band ripple, antialiasing low-pass filter with sharp roll-off, and 105 dB stop band attenuation at the Nyquist frequency.

For low-bandwidth and low-noise measurements, the device also offers a sinc response through a sinc5 filter. Both the wideband and sinc5 filters can be selected and run on a per-channel basis, and between the filter options, designers can improve the dynamic range by selecting from decimation rates of ×32, ×64, ×128, ×256, ×512, and ×1024, providing optimal noise performance to the required input bandwidth.

The 12 × 12mm AD7768 ADC operates over the -40 to +105degC industrial temperature range, and is targeted toward a variety of low-power applications, including data acquisition systems, instrumentation and industrial control loops, vibration and asset condition monitoring, 3-phase power quality analysis, and high-precision medical equipment. In addition, the AD7768 is supported by an evaluation board, which is also available to order through the Mouser Electronics website.
