AD706 is a dual-channel low-power bipolar op amp that has the low input bias current of a BiFET amplifier, but which offers a significantly lower IB drift over temperature

The AD705 is a low power bipolar op amp that has the low input bias current of a BiFET amplifier but which offers a significantly lower IB drift over temperature.

The document introduces the characteristics of the AD704 product, including high precision, low offset voltage, low offset voltage drift, low input bias current, low noise and low power consumption.

This document introduces the system architecture of the AD20msp410 GSM baseband processing chipset, including the algorithm signal processor, physical layer processor, microcontroller, baseband converter, radio subsystem, ROM, RAM, EEPROM, keyboard, and SIM card.

The AD7013 is a complete low power, CMOS, TIA IS-54 baseband receive port with single +5 V power supply. The part is designed to perform the baseband conversion of I and Q waveforms in accordance with the American (TIA IS-54) Digital Cellular Telephone system. The receive path consists of two high performance sigma-delta ADCs, each followed by a FIR digital filter. A primary and auxiliary set of IQ differential analog inputs are provided, where either can be selected as inputs to the sigma-delta ADCs. Also, a choice of two frequency responses are available for the receive FIR filters; a Root-Raised-Cosine filter for digital mode or a brick wall response for analog mode. Differential analog inputs are provided for both I and Q channels. On-chip calibration logic is also provided to remove either on-chip offsets or remove system offsets. A 16-bit serial interface is provided, interfacing easily to most DSPs. The receive path also provides a means to vary the gain of the receive path.

The AD7011 is a complete low power CMOS π/4 DQPSK modulator with single +5 V power supply. The part is designed to perform the baseband conversion of I and Q transmit wave- forms in accordance with the American Digital Cellular Tele- phone system (TIA IS-54).

The AD7010 is a complete low power, CMOS, π/4 DQPSK modulator with single +5 V power supply. The part is designed to perform the baseband conversion of I and Q transmit waveforms in accordance with the Japanese Digital Cellular Telephone system. The on-chip π/4 Differential Quadrature Phase Shift Keying (DQPSK) digital modulator, which includes the Root Raised Cosine filters, generates I and Q data in response to the transmit data stream. The AD7010 also contains ramp control envelope logic to shape the I and Q output waveforms when ramping up or down at the beginning or end of a transmit burst. Besides providing all the necessary logic to perform π/4 DQPSK modulation, the part also provides reconstruction filters to smooth the DAC outputs, providing continuous time analog outputs. The AD7010 generates differential analog outputs for both the I and Q signals. As it is a necessity for all digital mobile systems to use the lowest possible power, the device is designed in a low power manner.

The AD7008 is a CMOS DDS Modulator features a single +5 V supply, 32-Bit Phase Accumulator, On-Chip COSINE and SINE Look-Up Tables, On-Chip 10-Bit DAC, Frequency, Phase and Amplitude Modulation, Parallel and Serial Loading, Software and Hardware Power Down Options, 20 MHz and 50 MHz Speed Grades.
