AMC7932PHPR

ADCs/DACs - Special Purpose Overview

The AMC7932PHPR is a high-integration analog monitor and controller featuring 32 monotonic 12-bit DACs, a 12-bit SAR ADC, an internal temperature sensor, and GPIO ports. The DACs support programmable bipolar ranges including -10 V to 0 V, -5 V to 0 V, 0 V to 5 V, and 0 V to 10 V. The single-channel ADC operates at up to 250 kSPS with input ranges of 0 V to 5 V or 0 V to 2.5 V. It utilizes a 3-wire SPI-compatible interface operating from 1.65 V to 5.5 V and includes an internal 2.5-V reference. The device is housed in a 48-pin HTQFP (PHP) package.

ADCs/DACs - Special Purpose Feature Summary

• 32 Monotonic 12-Bit DACs: Programmable output ranges (-10 V to 0 V, -5 V to 0 V, 0 V to 5 V, 0 V to 10 V) with high current drive capability and autorange detection.
• 12-Bit SAR ADC: Multiplexed input with 250-kSPS sampling rate, supporting 0 V to 5 V and 0 V to 2.5 V input ranges with programmable out-of-range alarms.
• Integrated Sensors: Built-in temperature sensor with ±2.5°C maximum accuracy and 0.0625°C resolution; internal 2.5-V voltage reference.
• Flexible I/O: Six FlexIO pins configurable as analog inputs for the ADC or general-purpose I/O (GPIO).

ADCs/DACs - Special Purpose Applications

• Macro remote radio unit (RRU)
• Active antenna system mMIMO (AAS)
• Distributed antenna systems (DAS)
• Outdoor backhaul units
• Radar systems

ADCs/DACs - Special Purpose Procurement Notes

Verify the ordering suffix 'PHPR' corresponds to the HTQFP-48 package with a 1000-unit large tape-and-reel carrier. Confirm RoHS compliance and NIPDAU lead finish status via the manufacturer's packaging addendum. Ensure the specific part marking matches the AMC7932 designation without the 'F' variant suffix.

ADCs/DACs - Special Purpose Selection Notes

Select this component when designing high-density bias-control circuits for multichannel RF communication systems requiring LDMOS, GaAs, or GaN transistor technologies. The 3-wire SPI interface distinguishes it from the 4-wire AMC7932F variant. Verify that the required number of analog inputs does not exceed the six available FlexIO pins.

ADCs/DACs - Special Purpose Part Context

The AMC7932PHPR belongs to the Texas Instruments AMC7932 series of specialized data acquisition devices. It serves as an all-in-one solution for closed-loop system designs, reducing component count by integrating multiple DACs, an ADC, and control logic into a single 7.00 mm × 7.00 mm body size package.

ADCs/DACs - Special Purpose Replacement Considerations

The AMC7932FPHPR is a compatible alternative within the same family but features five FlexIO pins and requires a 4-wire SPI interface instead of the 3-wire mode used by the AMC7932PHPR.
