AMC7932PHPT

ADCs/DACs - Special Purpose Overview

The AMC7932PHPT is a high-density analog monitor and controller featuring 32 monotonic 12-bit DACs with programmable output ranges of –10 V to 0 V, –5 V to 0 V, 0 V to 5 V, and 0 V to 10 V. It integrates a 12-bit, 250-kSPS SAR ADC with input ranges of 0 V to 5 V and 0 V to 2.5 V, an internal 2.5-V reference, and a temperature sensor with ±2.5°C accuracy. The device includes six FlexIO pins configurable as ADC inputs or GPIOs, and communicates via a 3-wire SPI-compatible interface operating from 1.65 V to 5.5 V. It is housed in a 48-pin HTQFP (PHP) package.

ADCs/DACs - Special Purpose Procurement Notes

Verify the ordering suffix 'T' indicates a small tape-and-reel carrier containing 250 units. Confirm the specific package variant matches the required board layout for the 48-pin HTQFP PHP PowerPAD. Ensure the design supports the specified 1.65-V to 5.5-V SPI interface voltage levels and thermal requirements for the exposed pad soldering.

ADCs/DACs - Special Purpose Selection Notes

Select this component when high channel density is required for bias control in RF communication systems. The AMC7932 offers flexible DAC output ranges suitable for LDMOS, GaAs, and GaN transistor technologies. Consider the AMC7932F if a 4-wire SPI interface is preferred over the 3-wire mode supported by the standard AMC7932.

ADCs/DACs - Special Purpose Part Context

The AMC7932 belongs to Texas Instruments' analog monitor and controller family, designed to reduce component count in closed-loop systems. It serves as an all-in-one bias-control circuit for power amplifiers in multichannel RF applications. The PHPT designation specifies the 48-pin HTQFP package with a small tape-and-reel quantity of 250 units.

ADCs/DACs - Special Purpose Replacement Considerations

The AMC7932FPHPT is a compatible alternative that provides five FlexIO pins instead of six and utilizes a 4-wire SPI interface rather than the 3-wire mode.
