TLV0834IDR is a three-channel, low-power, high-speed ADC featuring 0.4 ENC and a sampling rate up to 12.5MSPS. It is a monolithic integrated circuit with a two-stage input amplifier and a single-slope successive-approximation register (SAR) converter. The ADC is suitable for a wide variety of applications including medical imaging and general-purpose data conversion. Its high sampling rate, low power consumption and small package size make it ideal for portable and battery-operated systems.

TLV0834IDR has two data acquisition channels for analog-to-digital conversion, each with a 12-bit resolution. An on-board reference voltage level can be adjusted with an external resistor, allowing the maximum range of the converted data to be adjusted with precision. The input range can be set to 0~5V, 0~10V, -5V~+5V, -10V~+10V, or any other range using an external resistor network.

The TLV0834IDR also features an output code inversion detection and an offset voltage adjustment. The offset voltage adjustment is used to trim the full scale code across temperature and other process variations. The output code inversion detection is used to detect any inversion of the output code due to a large input signal or a large offset voltage. This ensures accurate data conversion, even in the presence of large signals and offsets.

The TLV0834IDR uses a delta-sigma architecture for its ADC operation. This architecture includes a low-noise analog input stage, a 1-bit DAC, and a single-slope SAR. The ADC operates with a sampling rate of up to 12.5MSPS and a 1 bit resolution, and it achieves a powerful 0.4 Effective Number of Bits (ENOB).

The TLV0834IDR is ideal for precision data acquisition applications. It is available in a 5x5 mm QFN RoHS-compliant package, making it ideal for space-constrained designs. It consumes low power, featuring a supply current of only 12.6 mA at 3V, and it operates over a wide supply voltage range of 1.8V to 3.6V. It is guaranteed to operate over a temperature range of -40°C to 85°C.

In summary, the TLV0834IDR is a three-channel, low-power, high-speed ADC featuring 0.4 ENC and a sampling rate of up to 12.5MSPS. It is suitable for a range of data acquisition applications including medical imaging and general-purpose data conversion. Its high sampling rate, low power consumption and small package size make it ideal for portable and battery-operated systems.
