channel. The AMC7832 high level of integration
– 17ExternalAnalogInputs significantly reduces component count and simplifies
– 12BipolarInputs:-12.5-Vto+12.5-V closed-loopsystemdesigns.
Range The AMC7832 is ideal for multichannel applications
– 5HighPrecisionInputs:0to+5-VRange whereboardspace,size, andlowpower are critical.
– ProgrammableOut-of-RangeAlarms The AMC7832’s low power, high-integration and wide
• Internal+2.5-VReference operating temperature range make it an ideal all-in-
one, low-cost, bias control circuit for the power
• InternalTemperatureSensor
amplifiers (PA) found in multi-channel RF
– -40°Cto+125°COperation communication systems. The flexible DAC output
– ±2.5°CAccuracy ranges allow the device to be used as a biasing
solution for a large variety of transistor technologies
• EightGeneralPurposeI/OPorts(GPIOs)
such as LDMOS, GaAs and GaN. The AMC7832
• LowPowerSPICompatibleSerial Interface
feature set is similarly beneficial in general purpose
– 4-WireMode,+1.8-Vto+5.5-VOperation monitorandcontrolsystems.
