Introducing the AD7606C-18 8-Channel Digital Acquisition System from Analog Devices that provides increased measurement accuracy, evaluation board and samples available from Anglia

Date Published : 18/10/2021 Share with:

The AD7606C-18 from Analog Devices is an 18-bit, simultaneous sampling, analog-to-digital data acquisition system (DAS) with eight channels ideal for a wide range of monitoring, control and data acquisition applications

Each of the devices 8 channels contain analog input clamp protection, a programmable gain amplifier (PGA), a low-pass filter (LPF), and an 18-bit successive approximation register (SAR) analog-to-digital converter (ADC). The AD7606C-18 also contains a flexible digital filter, a low drift, 2.5 V precision reference, a reference buffer to drive the ADC, and flexible parallel and serial interfaces.

Functional Block Diagram

The AD7606C-18 operates from a single 5 V supply and accommodates a wide range of bipolar and unipolar single ended inputs and bipolar differential input ranges allowing sampling at throughput rates of 1 MSPS for all channels:

The integrated input clamp protection tolerates voltages up to ±21 V and the single supply operation, on-chip filtering, and high input impedance eliminate the need for external driver op amps, which require bipolar supplies. For applications with lower throughput rates, the AD7606C-18 flexible digital filter can be used to improve noise performance.

In hardware mode, the AD7606C-18 is fully compatible with the AD7608 and AD7609. In software mode, the following additional advanced features are available:

  • Analog input range selectable per channel with added ranges available
  • High bandwidth mode (220 kHz) selectable per channel
  • Additional oversampling options with an oversampling ratio up to 256
  • System gain, system offset, and system phase calibration, per channel
  • Analog input open circuit detector
  • Diagnostic multiplexer
  • Monitoring functions (serial peripheral interface (SPI) invalid read and write, cyclic redundancy check (CRC), busy stuck monitor, and reset detection)
  • Note that throughout the data sheet, multifunction pins, such as the RD/SCLK pin, are referred to either by the entire pin name or by a single function of the pin, for example, the SCLK pin, when only that function is relevant.


The device also features onboard Calibration and Diagnostics including per channel system phase, offset, and gain calibration, analog input open circuit detection feature, self-diagnostics and monitoring features and CRC error checking on read and write data and registers.

Evaluation Board

The EVAL-AD7606CFMCZ evaluation board is available to support designers using the AD7606C-18, this fully featured evaluation board allows users to evaluate the features of both the AD7606C-18 and AD7606C-16 analog-to-digital converters (ADCs). The evaluation board also includes the ADP7118 5 V and 3.3 V low noise, low dropout (LDO) linear regulators and an ADR4525 high precision, band gap voltage reference.
The EVAL-AD7606CFMCZ is controlled using the EVAL-SDP-CH1Z (SDP-H1) system demonstration platform (SDP) through the USB port of a PC using the Analysis | Control | Evaluation (ACE) software which can be downloaded from Analog Devices.

The AD7606C-18 18-bit, 8 channel, simultaneous sampling, analog-to-digital data acquisition system (DAS) is suitable for a range of applications including Power line monitoring, Protective relays, Multiphase motor control, Instrumentation and control systems and Data acquisition systems.
