Data Acquisition - Analog to Digital Converters (ADC) are vital devices in many modern electronics systems. The IDTADC1207S080HW-C28 ADC is a versatile low-power, 8-bit CMOS device specifically designed to sample and convert analog input signals into digital data.

The IDTADC1207S080HW-C28 is suitable for applications including battery-powered systems, portable medical devices and embedded sensing systems, among others. It is a high-speed, low-power CMOS converter that provides a single 8-bit output for the active input range of 0V to +4.095V.

The working principal of the IDTADC1207S080HW-C28 involves the use of a successive approximation register (SAR) to generate a digital code proportional to the analog input voltage. Upon power-up, the device performs an internal calibration sequence and then enters a low-power sleep mode. When a valid trigger is detected, the device wakes up and codes the analog input. At the end of the conversion, it powers down and stores the 8-bit digital result.

The IDTADC1207S080HW-C28 features an integrated sample-and-hold amplifier (SHA) and an on-chip clock generating system. The SHA has an input boost circuitry that amplifies low-level analog inputs, allowing conversions on weak signals with less than 8 mV peak-to-peak. The device includes an on-chip temperature sensor that provides an automatic means to compensate the device performance with respect to temperature variations.

The device also has a wide range of programmable features such as variable sampling rates, single-cycle conversion mode, power down modes and a choice of clock sources. It can be programmed for single-ended, differential or double-ended conversions and is available with a choice of 8, 10 and 12-bit resolution.

The low power-cost of the IDTADC1207S080HW-C28 makes it ideally suited for embedded systems that require low power consumption without compromising performance. With an operating power of between 1.1 and 3.3V and a sleep current of as low as 20µA, the IDTADC1207S080HW-C28 is a highly efficient and cost-effective ADC for many applications.
