TPA7836B中文资料Analog monitor control solution数据手册3PEAK规格书

描述 Description

The TPA7836B is a highly integrated, low power consumption, analog monitor and control solution, it includes a 21-channel, 12bits ADC, sixteen 12-bits DACs with programmable output ranges, an internal reference, eight GPIOs and a local temperature sensor, the high integration significantly reduces component counts and simplifies the system design with small pace, low power, high reliability.

The low power, very high integration and wide operation temperature range of this device make it suitable for an allin-one, low cost, bias-control circuit for the power amplifiers found in multi-channel RF communication systems, the flexible DAC output ranges allow the device to be used as a biasing solution for the large variety of transistor technologies, such as LDMOS, GaN, GaAs.
