Data acquisition is an important and essential discipline in many fields of engineering and technology. For example, in signal processing and telecommunication, in health and medical instrumentation, in automotive and aerospace engineering, in defense and military systems, in imaging and radar applications, and in other areas of applied research. The CS5361-DZZ is a single-ended, low-voltage differential-signal (LVDS) low-power, high-density analog-to-digital converter (ADC).

The CS5361-DZZ is a hugely popular part with many applications. It provides an outstanding sampling rate, resolution and signal-to-noise ratio (SNR). These are combined with excellent low-noise and high-timing accuracy performance. The wide range of its input signal range (≤ 2Vpp) allows for a variety of signal conditioning and applications.

The CS5361-DZZ is optimized for high-speed, low-power applications, such as mobile medical applications, data converters for satellite communications, in-car infotainment systems, baseband video recorders, and motor control solutions. Its low noise and low power make it ideal for many tasks where a low power budget and low noise are paramount, such as portable ultrasound scanners and medical instrumentation, audio front ends and engines, toys, and remote sensors.

The unique feature of the CS5361-DZZ is its self-calibrating architecture that reduces power consumption, noise, and data converter setup and test time. This innovative architecture helps to achieve the rating of a maximum resolution of 14 bits, with a SNR of 61 dB and a sampling rate of 927 kSPS. The device also features an adjustable gain up to 16x, allowing for a wider dynamic input range.

The CS5361-DZZ also features a low-power shutdown mode and low-power sleep mode. In sleep mode, the device will shut down power but maintain its internal registers, allowing for wake-up signals and lower power consumption in standby mode. The device also features an on-chip reference (Vref) for current operation, eliminating the need for external circuitry and providing shorter setup time.

In addition, the CS5361-DZZ includes a built-in programmable gain amplifier (PGA), two internal passthroughs to reduce power requirements, a single-ended step-down current-mode reference (Vref), and a low-pass filter. The gain range is adjustable between 1x and 16x, with a maximum SNR of 61 dB. The programmable gain amplifier helps to control gain and offset variations, while the passthroughs reduce power consumption. The low-pass filter helps to remove high-frequency noise from the input signal.

The working principle of the CS5361-DZZ is based on a double conversion process. The first step involves the analog-to-digital conversion of the input signal, which is converted to a series of high-frequency, digital signals. These digital signals are then grouped into blocks of eight bits and are clocked out by the ADC at the same rate of the input signal. The second step involves decoding the digital signals and converting them into a multiplexed output. Finally, the analog output is generated from the digital output.

The CS5361-DZZ is an excellent choice for a wide range of applications requiring a high-performance, low-power ADC. Its unique combination of internal calibration, low-noise and high-timing accuracy make it the ideal choice for many data acquisition, communication, and portable medical instrumentation applications. The wide range of input signals and adjustable gains contribute further to its versatility and superior performance.
