ADS7960SRHBT 개요
An SAR ADC is a type of analog-to-digital converter that uses a binary search algorithm to convert an analog input signal into a digital representation. It is known for its high speed and low power consumption, making it ideal for applications such as data acquisition, industrial process control, and portable instrumentation. The SAR architecture is widely used in multichannel systems where multiple analog signals need to be digitized sequentially.
Key features of the ADS7960SRHBT include a 1-MSPS sampling rate, 12 input channels, and a serial peripheral interface (SPI) for communication with microcontrollers or digital signal processors. The device operates from a single 2.7V to 5.25V power supply, and its micro-power consumption makes it suitable for battery-powered applications. The ADC also features a built-in reference and a programmable gain amplifier, reducing external component count.
The ADS7960SRHBT uses a capacitive DAC architecture with a successive approximation register, providing accurate conversion with low power dissipation. The device includes a track-and-hold circuit that samples the analog input, and the conversion result is output serially via the SPI interface. The ADC supports both single-ended and pseudo-differential input configurations, offering flexibility in system design.
Typical applications for the ADS7960SRHBT include data acquisition systems, industrial process control, motor control, and portable instrumentation. Its 12-channel input capability allows monitoring of multiple sensors or signals, while the SPI interface simplifies connection to a wide range of microcontrollers. The device is also suitable for battery-powered devices due to its low power consumption.
When designing with the ADS7960SRHBT, it is important to provide a clean analog supply and proper decoupling to achieve the specified performance. The reference input should be bypassed with a capacitor, and the analog input signals should be buffered if they have high source impedance. The SPI interface should be operated at the correct clock frequency to ensure accurate data transfer.

설계 노트
Provide a clean analog supply (AVDD) and digital supply (DVDD) with proper decoupling. Use 0.1uF and 10uF capacitors close to the power pins. The reference input (REF) should be bypassed with a 1uF capacitor to ground to ensure stable reference voltage.
Place the ADC close to the analog signal sources to minimize trace length and reduce noise pickup. Use a solid ground plane and separate analog and digital ground planes if possible. Ensure the exposed thermal pad is soldered to the PCB for proper heat dissipation.
Avoid driving the analog inputs with high source impedance, as this can cause sampling errors. Use a buffer amplifier if the source impedance is high. Also, ensure the SPI clock frequency does not exceed the maximum specified in the datasheet to avoid data corruption.
