The AD5930 is a waveform generator with programmable frequency sweep and output burst capability. Utilizing embedded digital processing that allows enhanced frequency control, the device generates synthesized analog or digital frequency-stepped waveforms. Because frequency profiles are preprogrammed, continuous write cycles are eliminated and thereby free up valuable DSP/microcontroller resources. Waveforms start from a known phase and are incremented phase continuously, which allows phase shifts to be easily determined. Consuming only 8 mA, the AD5930 provides a convenient low power solution to waveform generation.The AD5930 can be operated in a variety of modes. In continuous output mode, the device outputs the required frequency for a defined length of time and then steps to the next frequency. The length of time the device outputs a particular frequency is either preprogrammed and the device increments the frequency automatically, or, alternatively, is incremented externally via the CTRL pin. In burst mode, the device outputs its frequency for a length of time and then returns to midscale for a further predefined length of time before stepping to the next frequency. When the MSBOUT pin is enabled, a digital output is generated.To program the device, the user enters the start frequency, the increment step size, the number of increments to be made, and the time interval that the part outputs each frequency. The frequency sweep profile is initiated, started, and executed by toggling the CTRL pin.A number of different sweep profiles are offered. Frequencies can be stepped in triangular-sweep mode, which continuously sweeps up and down through the frequency range. Alternatively, in saw-sweep mode, the frequency is swept up through the frequency range, but returns to the initial frequency before executing the sweep again. In addition, a single frequency or burst can be generated without any sweep.The AD5930 is written to via a 3-wire serial interface, which operates at clock rates up to 40 MHz. The device operates with a power supply from 2.3 V to 5.5 V. Note that AVDD and DVDD are independent of each other and can be operated from different voltages. The AD5930 also has a standby function, which allows sections of the device that are not being used to be powered down.The AD5930 is available in a 20-lead pb-free TSSOP package.Applications Frequency sweeping/radar Network/impedance measurements Incremental frequency stimulus Sensory applications Proximity and motion BFSK Frequency bursting/pulse trains

These input channels include multiple external current inputs, external voltage inputs, and internal channels. The internal channels allow diagnostic measurements of the internal supply voltages, die temperature, and reference voltages.The current inputs include two TIAs with programmable gain and load resistors for measuring different sensor types. The first TIA, referred to as the low power TIA, measures low bandwidth signals. The second TIA, referred to as the high speed TIA, measures high bandwidth signals up to 200 kHz.An ultra low leakage, programmable switch matrix connects the sensor to the internal analog excitation and measurement blocks. This matrix provides an interface for connecting external transimpedance amplifier resistors (RTIAs) and calibration resistors. The matrix can also be used to multiplex multiple electronic measurement devices to the same wearable electrodes.A precision 1.82 V and 2.5 V on-chip reference source is available.

Alternatively, an external reference up to 3.3 V can be used.The conversion process and data acquisition use standard control inputs that allow simple interfacing to microprocessors or digital signal processors (DSPs). The devices are compatible with 1.8 V, 2.5 V, and 3.3 V interfaces, using a separate logic supply.The AD7383 and the AD7384 are available in a 16-lead lead frame chip scale package (LFCSP) with operation specified from ?40?C to +125?C.Multifunction pin names may be referenced by their relevant function only.PRODUCT HIGHLIGHTS Dual simultaneous sampling and conversion with two complete ADC functions. Pin-compatible product family. High 4 MSPS throughput rate. Space saving 3 mm ? 3 mm LFCSP. Integrated oversampling block to increase dynamic range, reduce noise, and reduce SCLK speed requirements. Pseudo differential analog inputs. Small sampling capacitor reduces amplifier drive burden.APPLICATIONS Motor control position feedback Motor control current sense Sonar Power quality Data acquisition systems Erbium doped fiber amplifier (EDFA) applications I and Q demodulation

The AD7386/AD7387/AD7388 are 16-bit, 14-bit, and 12-bit dual, simultaneous sampling, high speed, successive approximation register (SAR), analog-to-digital converters (ADCs) that operate from a 3.0 V to 3.6 V power supply and feature throughput rates of up to 4 MSPS. The analog input types are single-ended and are sampled and converted on the falling edge of CS.The AD7386/AD7387/AD7388 have an on-chip sequencer and integrated on-chip oversampling block to improve dynamic range and reduce noise at lower bandwidths.
