MAX11616EEE+

Data Acquisition - Analog to Digital Converters (ADC)

The MAX11616EEE+ is an analog-to-digital converter offering the highest resolution, accuracy, and speed available in an integrated, monolithic, low-power device. It is designed to convert electrical signals with minimal signal distortion and fast update speed. The device has a power efficiency of up to 1.4 mW/channel, which is the lowest power consumption of any ADC currently available.

The device SAMPLE/HOLD circuit is implemented to allow connection of multiple input channels while minimizing signal distortion. The high-resolution multi-channel inputting mechanism features decoupling and spike cancellation, both of which are essential for clean ADC operation. Additionally, the device features a dual-conversion architecture that boasts a wide input range and output range and low noise.

The MAX11616EEE+ is a highly accurate 12-bit analog-to-digital converter and provides users with precision conversion performance. It utilizes advanced peripheral circuitry to minimize distortion and errors during conversion. Its DNL/INL performance makes it appropriate for applications where precision is critical. The ADC’s large input range allows for more flexibility when measuring signals from a variety of input sources.

The device provides users with maximum performance at ultra-high resolution and a wide dynamic range while staying within power and space constraints. The data sheet states that the device can convert up to three channels simultaneously, with a conversion rate of up to 400 ksps. The device has a wide power supply range of 1.7V to 5.5V, allowing it to operate with both 3.3V and 5V logic.

The working principle of the MAX11616EEE+ is based on the successive approximation technique where each successive approximation of the input voltage is compared to the reference voltage. In an ideal ADC, this comparison should be instantaneous so that the ADC can be updated quickly. However, the successive approximation technique is a relatively slow method, slowing down the overall performance of the ADC.

The MAX11616EEE+ supports external clock sources, allowing for higher speeds of up to 20 MHz with two conversion stages. The device also supports various power modes and operating temperatures ranging from -40°C to +85°C. The ADC is equipped with an on-chip 1.2V reference and can be down-programmed to a 1.0V reference to save power and improve noise performance.

With its varied features and specifications, the MAX11616EEE+ is suitable for a wide range of applications, including industrial process control, test equipment, medical imaging, and military embedded systems. The ADC’s integrated features also make it an ideal choice for applications that need an embedded analog-to-digital converter.
