The AD6623 is a four channel Transmit Signal Processor (TSP) that creates high bandwidth data for Transmit Digital-to-Analog Converters (TxDAC®s) from baseband data provided by a Digital Signal Processor (DSP). Modern TxDACs have achieved sufficiently high sampling rates, analog bandwidth, and dynamic range to create the first Intermediate Frequency (IF) directly. The AD6623 synthesizes multi-carrier and multi-standard digital signals to drive these TxDACs. The RAM-based architecture allows easy reconfiguration for multi-mode applications. Modulation, pulse-shaping and anti-imaging filters, static equalization, and tuning functions are combined in a single, cost-effective device. Digital IF signal processing provides repeatable manufacturing, higher accuracy, and more flexibility than comparable high dynamic range analog designs.The AD6623 is pin compatible to the AD6622 and can operate in AD6622 compatible control register mode. Each TSP has five cascaded signal processing elements: a programmable interpolating RAM Coefficient Filter (RCF), a programmable Scale and Power Ramp, a programmable 5th order Cascaded Integrator Comb (CIC5) interpolating filter, a flexible 2nd order Re-Sampling Cascaded Integrator Comb filter (rCIC2), and a Numerically Controlled Oscillator/tuner (NCO). The AD6623 has four identical digital TSPs complete with synchronization circuitry and cascadable wideband channel summation. The outputs of the four TSPs are summed and scaled on-chip. In multi-carrier channel wideband transmitters, a bi-directional bus allows the Parallel (wideband) IF Input/Output to drive a second DAC. In this operational mode two AD6623 channels drive one DAC and the other two AD6623 channels drive a second DAC. Multiple AD6623s may be combined by driving the INOUT[17:0] of the succeeding with the OUT[17:0] of the preceding chip. The INOUT[17:0] can alternatively be masked off by software to allow preceding AD6623s outputs to be ignored.Each channel accepts input data from independent serial ports that may be connected directly to the serial port of Digital Signal Processor (DSP) chips. The AD6623 utilizes a 3.3V I/O power supply and a 2.5V core power supply. All I/O pins are 5V tolerant. All control registers and coefficient values are programmed through a generic microprocessor interface. Intel and Motorola microprocessor bus modes are supported. All inputs and outputs are LVCMOS compatible.Applications Cellular/PCS Base Stations Micro/Pico Cell Base Stations Wireless Local Loop Base Stations Multicarrier, Multimode Digital Transmit GSM, EDGE, IS136, PHS, IS95, TDS CDMA, UMTS, CDMA2000 Phased Array Beam Forming Antennas Software Defined Radio Tuning Resolution Better than 0.025 Hz Real or Complex Outputs

The AD737 is a low power, precision, monolithic, true rms-to-dc converter. It is laser trimmed to provide a maximum error of ±0.2 mV ± 0.3% of reading with sine wave inputs. Furthermore, it maintains high accuracy while measuring a wide range of input waveforms, including variable duty cycle pulses and triac (phase) controlled sine waves. The low cost and small physical size of this converter make it suitable for upgrading the performance of non-rms precision rectifiers in many applications. Compared to these circuits, the AD737 offers higher accuracy at equal or lower cost.The AD737 computes the rms value of both the ac and dc input voltages, and is ac-coupled by adding an input capacitor. In this mode, the AD737 can resolve input signal levels of 100 μV rms or less, despite variations in temperature or supply voltage. High accuracy is maintained for input waveforms with crest factors of 1 to 3 and crest factors at 2.5% or less with respect to full-scale input level.The AD737 has no output buffer amplifier, thereby significantly reducing dc offset errors occurring at the output, which makes the device highly compatible with high input impedance ADCs.Requiring only 160 μA of power supply current, the AD737 is optimized for use in portable multimeters and other battery-powered applications. In power-down mode, the standby supply current in is typically 25 μA.The AD737 has both high (1012 Ω) and low impedance input options. The high-Z FET input connects high source impedance input attenuators, and a low impedance (8 kΩ) input accepts rms voltages of up to 0.9 V while operating from the minimum power supply voltage of ±2.5 V. The two inputs can be used either single ended or differentially.The AD737 achieves 1% of reading error bandwidth, exceeding 10 kHz for input amplitudes from 20 mV rms to 200 mV rms, while consuming only 0.72 mW.The AD737 is available in two performance grades. The AD737J and AD737K grades operate over the commercial temperature range of 0°C to 70°C. The AD737JR-5 is tested with supply voltages of ±2.5 V dc.

Only one external component, an averaging capacitor, is required for the AD737 to perform true rms measurement. The standby power consumption of 125 μW makes the AD737 suitable for battery-powered applications.

The AD7542 is a precision 12-bit CMOS multiplying DAC designed for direct interface to 4- or 8-bit microprocessors.The functional diagram shows the AD7542 to consist of three 4-bit data registers, a 12-bit DAC register, address decoding logic and a 12-bit CMOS multiplying DAC. Data is loaded into the data registers in three 4-bit bytes, and subsequently transferred to the 12-bit DAC register. All data loading or data transfer operations are identical to the WRITE cycle of a static RAM. A clear input allows the DAC register to be easily reset to all zeros when powering up the device.
