The AD7767/AD7767-1/AD7767-2 are high performance, 24-bit, oversampled SAR analog-to-digital converters (ADCs). The AD7767/AD7767-1/AD7767-2 combine the benefits of a large dynamic range and input bandwidth, consuming 15 mW, 10.5 mW, and 8.5 mW power, respectively, and are contained in a 16-lead TSSOP package.

Ideal for ultralow power data acquisition (such as PCI- and USB-based systems), the AD7767/AD7767-1/AD7767-2 provide 24-bit resolution. The combination of exceptional SNR, wide dynamic range, and outstanding dc accuracy make the AD7767/AD7767-1/AD7767-2 ideally suited for measuring small signal changes over a wide dynamic range. This is particularly suitable for applications where small changes on the input are measured on larger ac or dc signals. In such an application, the AD7767/AD7767-1/AD7767-2 accurately gather both ac and dc information.

The AD7767/AD7767-1/AD7767-2 include an on-board digital filter (complete with linear phase response) that acts to elimi-nate out-of-band noise by filtering the oversampled input voltage. The oversampled architecture also reduces front-end antialias requirements. Other features of the AD7767 include a SYNC/PD (synchronization/power-down) pin, allowing the synchronization of multiple AD7767 devices. The addition of an SDI pin provides the option of daisy chaining multiple AD7767 devices.

The AD7767/AD7767-1/AD7767-2 operate from a 2.5 V supply using a 5 V reference. The devices operate from −40°C to +105°C.

Applications

  • Low power PCI/USB data acquisition systems
  • Low power wireless acquisition systems
  • Vibration analysis
  • Instrumentation
  • High precision medical acquisition

AD7767 Evaluation Board

Features and Benefits

  • Full-featured evaluation board for the:
    • AD7767
    • AD7767-1
    • AD7767-2
  • CED compatible
  • Standalone capability
  • On-board analog buffering and voltage reference
  • Various linking options

  • Linearity Evaluation

Product Detail

The AD7767 has a maximum output data rate of 128 KHz. The derivatives AD7767-2 operate at a max speed of 64 KHz, with the AD7767-2 offering a max speed of 32 KHz. The AD7767-1 and AD7767-2 versions digitally filter more rigorously, meaning that greater noise performance is achieved, trading off on output data rate.


All the AD7767 devices (AD7767, AD7767-1, AD7767-2) offer 18-bit linearity (3ppm).


Full details on the versions of the AD7767 are available in the AD7767 data sheet, which is available from Analog Devices, Inc., and should be consulted in conjunction with this data sheet when using the evaluation board.


Please note: This Evaluation software does not run on Windows 8 or Windows 10 (USB driver is non-compliant with OS >Windows 7).
