TPA7836B-QP

ADCs/DACs - Special Purpose Overview

The TPA7836B-QP is a highly integrated, low-power analog monitor and control solution featuring sixteen 12-bit monotonic DACs and one 12-bit SAR ADC. The DACs offer selectable output ranges of −10 to 0 V, −5 to 0 V, 0 to 5 V, and 0 to 10 V with high current drive capability up to ±10 mA. The ADC supports 21 external analog inputs, including 16 bipolar channels (−12.5 to 12.5 V) and five high-precision unipolar channels (0 to 5 V). Additional features include eight GPIOs, an internal 2.5-V reference, and a temperature sensor accurate to ±7.5°C. It operates from −40°C to 125°C in a TQFP10X10-64 package.

ADCs/DACs - Special Purpose Procurement Notes

Verify that the ordering suffix '-QP' corresponds to the specific package variant or qualification level defined in the manufacturer's official order information section. Confirm the device meets the required automotive or industrial reliability standards if applicable, as indicated by the suffix designation in the datasheet.

ADCs/DACs - Special Purpose Selection Notes

Select this component for multi-channel RF communication systems requiring integrated bias control and monitoring. Ensure the application utilizes the available DAC groups (A-D) which share common range settings. Verify that the input voltage ranges of the monitored signals align with the bipolar (-12.5V to 12.5V) or unipolar (0 to 5V) ADC input capabilities.
