AMC7836IPAP

ADCs/DACs - Special Purpose Overview

The AMC7836IPAP is a high-density, low-power analog monitor and control solution manufactured by Texas Instruments. It integrates a 21-channel 12-bit ADC, 16 bipolar DACs, an internal voltage reference, a local temperature sensor, and eight GPIO ports. The device operates within a supply voltage range of -12.5 V to 0 V for negative rails, 1.8 V to 5.5 V for logic, and 4.7 V to 12.5 V for positive rails. It functions reliably across a temperature range of -40°C to +125°C and is housed in a 64-pin HTQFP package with a PowerPAD thermal pad.

ADCs/DACs - Special Purpose Feature Summary

• Integrates 16 monotonic 12-bit DACs with programmable output ranges (-10V to 0V, -5V to 0V, 0V to 5V, 0V to 10V) and high current drive capability up to ±15mA.
• Includes a 21-channel 12-bit SAR ADC featuring 16 bipolar inputs (-12.5V to 12.5V) and 5 high-precision inputs (0V to 5V).
• Features a 2.5V internal voltage reference and a local temperature sensor with ±2.5°C accuracy over the operating range.
• Utilizes a low-power 4-wire SPI interface compatible with 1.8V to 5.5V logic levels.

ADCs/DACs - Special Purpose Applications

• Bias control circuits for power amplifiers in multi-channel RF communication systems.
• Monitoring and control solutions for LDMOS, GaAs, and GaN transistor technologies.
• General-purpose analog monitoring and control systems requiring high channel density.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'IPAP' corresponds to the standard tray packaging configuration as indicated by distributor listings. Confirm that the HTQFP-64 package variant meets thermal requirements for the intended application environment. Ensure compatibility with the 4-wire SPI protocol when integrating with host controllers.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a single IC must replace multiple discrete monitors and controllers to reduce board space. The integrated 21-channel ADC and 16-channel DAC allow for comprehensive system management without external multiplexers. Verify that the required DAC output ranges align with the available programmable options.

ADCs/DACs - Special Purpose Part Context

The AMC7836 belongs to Texas Instruments' Analog Monitor and Control (AMC) product family. This series provides various configurations of ADCs, DACs, and GPIOs to address different channel count and resolution needs. The IPAP designation identifies the specific pinout, package type, and commercial/industrial grade variant within this lineup.

ADCs/DACs - Special Purpose Replacement Considerations

Check for other members of the AMC783x family, such as the AMC7834 or AMC7932, if channel counts or additional features differ from project requirements. Ensure any substitute maintains the same HTQFP-64 footprint and electrical specifications for direct replacement.
