Data Acquisition - Analog to Digital Converters (ADCs) are critical components used to convert an analog signal into digital format. The THS1209IDA is an integrated analog-to-digital converter (ADC) solution with 10-bit accuracy for low power applications. By utilizing its on-chip Charge Pump and a low noise amplifier, it provides a high dynamic range at up to 100kHz. The THS1209IDA is ideal for use in systems that require low-noise signal conditioning and signal-to-noise ratio (SNR) for industrial, medical, and consumer applications.

The THS1209IDA features a wide input common mode range of 0 V to 4V and low supply voltage of 2.7 V to 5.5 V, as well as a low power consumption of 3.5mW, making it suitable for low-power and small-size applications. It also comes with integrated voltage reference, an internal clock, and on-chip sample-and-hold a key feature for multiplexer implementations.

The device has an LCD sample-hold and input buffer capability, as well as an internal offset adjustment, and a high sample rate capability of 40 MHz. The THS1209IDA also features a variety of digital features, optimized for ultralow power and fast settling including low noise and low resolution linearity, and low power digital calibration.

One of the key features of the THS1209IDA is its wide input bandwidth of up to 30 MHz or 20 MHz depending on the application, as well as its fast settling time ranging from 20 us to 1 us. It also has an internal digital calibration capability that can be used to provide improved performance in analog applications that require precise measurements. Additionally, it has an integrated temperature and supply voltage compensation, which further ensures better performance and accuracy, even on changing environmental conditions.

The THS1209IDA consists of an integrated 10-bit analog-to-digital converter, which is powered from a single 1.8V to 3.3V power supply. It has a peak conversion rate of 160 kHz, which can be achieved when a slow clock of 1 MHz is used. It also has an integrated low noise amplifier, charge-pump level shifting, and multiple sample and hold functionality. Its data outputs are multiplexed depending on the number of conversions to be made.

The THS1209IDA also includes innovative design features such as the patented EMEA (Electronically Momentarily Extracting Analog) technology, which is capable of reducing digital-to-analog conversion time by up to 84%. The EMEA technology helps to minimize the jitter caused by components, reduce their offset errors and drift, thereby improving the system’s accuracy, stability and precision. Additionally, it also reduces the power consumption in comparison to other A/D Converters.

The internal architecture of the THS1209IDA consists of multiplexer, charge pump, reference, precision amplifier, and digital calibrator. The reference (REF) provides an accuracy of 0.3% at an ambient temperature of 25°C. The precision amplifier couples the input voltage to the multiplexer. The high impedance of the amplifier ensures that the input source does not affect the quality of the signal. The charge pump level shifting helps to reduce power dissipation and increase dynamic range. The circuit also features a high-precision source calibration to adjust the gain and offset error resulting from mismatches between components as well as from leakage currents. The powerful digital calibrator allows for fast and accurate operation.

The THS1209IDA offers a variety of advantages, making it a preferred choice for many applications. It is ideal for use in low noise, accurate, and fast settling applications, and its wide range of features makes it easy to be integrated into different types of system designs. The device is also suitable for high-performance and high-speed applications, such as medical imaging, automotive data acquisition, industrial process control, and handheld devices. Its high reliability and accuracy, coupled with low power consumption, makes it highly suitable for use in a variety of industrial and consumer applications.
