Description for the AMC7834

The AMC7834 device is a highly-integrated, low-power, analog monitoring and control solution for power-amplifier (PA) biasing capable of temperature, current and voltage supervision.

The device integrates a multi-channel, 12-bit analog-to-digital converter (ADC); eight, 12-bit digital-to-analog converters (DAC); four high-side current-sense amplifiers that can be optionally set to operate as part of four independent closed-loop drain-current controllers; an accurate on-chip temperature sensor and two remote temperature-sensor diode drivers; four configurable general-purpose I/O ports (GPIOs); and an accurate internal reference. The high level of integration significantly reduces component count and simplifies PA-biasing system designs.

The function integration and wide operating-temperature range of the device make it suitable as an all-in-one, low-cost, bias control-circuit for PAs found in multi-channel RF communication systems. The flexible DAC output ranges and wide common mode voltage current sensors allow the device to be used as a biasing solution for a large variety of transistor technologies such as LDMOS, GaAs, and GaN. The AMC7834 feature set is similarly beneficial in general-purpose monitor and control systems.

For applications that require a different channel-count, additional features, or converter resolutions, Texas Instruments offers a complete family of analog monitor and control (AMC) products. For more information, go to www.ti.com/amc.

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

A custom reel is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.

Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.

TI often ships tube or tray devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
