The AD7992 is a 12-bit, low power, successive approximation ADC with an I2 C-compatible interface. The part operates from a single 2.7 V to 5.5 V power supply and features a 2 ?s conversion time. The part contains a 2-channel multiplexer and track-and-hold amplifier that can handle input frequencies up to 11 MHz. The AD7992 provides a 2-wire serial interface compatible with I2C interfaces. The part comes in two versions, the AD7992-0 and the AD7992-1, and each version allows for at least two different I2C addresses. The AD7992-0 supports standard and fast I2C interface modes, and the AD7992-1 supports standard, fast, and high speed I2C interface modes. The AD7992 normally remains in a shutdown state while not converting, and powers up only for conversions. The conversion process can be controlled using the CONVST pin, by a command mode where conversions occur across I2C write operations, or an automatic conversion interval mode selected through software control. The AD7992 requires an external reference in the range of 1.2 V to VDD. This allows the widest dynamic input range to the ADC. On-chip limit registers can be programmed with high and low limits for the conversion result, and an open-drain, out-of-range indicator output (ALERT) becomes active when the conversion result violates the programmed high or low limits. This output can be used as an interrupt.PRODUCT HIGHLIGHTS 2 ?s conversion time and low power consumption. I2C-compatible serial interface with pin-selectable addresses. Two AD7992 versions allow five AD7992 devices to be connected to the same serial bus. The part features automatic shutdown while not converting to maximize power efficiency. Current consumption is 1 ?A max when in shutdown mode at 3 V. Reference can be driven up to the power supply. Out-of-range indicator that can be software disabled or enabled. One-shot and automatic conversion rates. Registers store minimum and maximum conversion results.

Demonstration circuit 3162A is a 18V, 10A synchronous step-down Silent Switcher® with spread spectrum frequency modulation featuring the LT8642-1. The demo board is designed for 1.2V output from a 2.8V to 18V input. The LT8642-1 is a compact, low emission, high efficiency, and high speed synchronous monolithic stepdown switching regulator. Special Silent Switcher architecture minimizes EMI emissions. Selectable spread spectrum mode can further improve EMI performance. Fast minimum on-time of 20ns enables high VIN to low VOUT conversion at high frequency. The LT8642-1 switching frequency can be programmed either via a resistor or external clock over a 200kHz to 3MHz range. The default frequency of demo circuit 3162A is 2MHz. The LT8642-1 SYNC/MODE pin on the demo board is grounded (JP1 at BURST position) by default for low ripple Burst Mode® operation. Spread spectrum mode and forced continuous mode can be selected respectively by moving JP1 shunt. To synchronize to an external clock, move JP1 to FCM/SYNC and apply the external clock to the SYNC terminal. The LT8642-1 data sheet gives a complete description of the part, operation, and application information. The data sheet must be read in conjunction with this demo manual for demo circuit 3162A. The LT8642-1 is assembled in a 3mm × 4mm LQFN package with exposed pads for low thermal resistance. The layout recommendations for low EMI operation and maximum thermal performance are available in the data sheet section Low EMI PCB Layout and Thermal Considerations.

The ADXRS623 is a complete angular rate sensor (gyroscope)that uses the Analog Devices, Inc. surface-micromachiningprocess to create a functionally complete and low cost angularrate sensor integrated with all required electronics on one chip.The manufacturing technique for this device is the same highvolume BiMOS process used for high reliability automotiveairbag accelerometers.The ADXRS623 is an automotive grade gyroscope. Automotive grade gyroscopes have more extensive guaranteed min/max specifications due to automotive testing.The output signal, RATEOUT (1B, 2A), is a voltageproportional to the angular rate about the axis that is normal tothe top surface of the package. The output is ratiometric withrespect to a provided reference supply. A single externalresistor between SUMJ and RATEOUT can be used to lowerthe scale factor. An external capacitor sets the bandwidth. Otherexternal capacitors are required for operation.A temperature output is provided for compensation techniques.Two digital self-test inputs electromechanically excite thesensor to test proper operation of both the sensor and the signalconditioning circuits.
