The AD7877 is a 12-bit, successive approximation ADC with a synchronous serial interface and low on resistance switches for driving touch screens. The AD7877 operates from a single 2.7 V to 5.25 V power supply (functional operation to 2.2 V), and features throughput rates of 125 kSPS. The AD7877 features direct battery measurement on two inputs, temperature and touch-pressure measurement.The AD7877 also has an on-board reference of 2.5 V. When not in use, it can be shut down to conserve power. An external reference can also be applied and varied from 1 V to +VCC, with an analog input range of 0 V to VREF. The device includes a shutdown mode that reduces its current consumption to less than 1 μA.To reduce the effects of noise from LCDs, the acquisition phase of the on-board ADC is controlled via the STOPACQ pin. User-programmable conversion controls include variable acquisition time and first conversion delay. Up to 16 averages can be taken per conversion. There is also an on-board DAC for LCD back-light or contrast control. The AD7877 runs in either slave or master mode using a conversion sequencer and timer. It is ideal for battery-powered systems such as personal digital assistants with resistive touch screens and other portable equipment.The part is available in a 32-lead lead frame chip scale package (LFCSP), and a 25-ball wafer level chip scale package (WLCSP).

The AD8009 is an ultrahigh speed current feedback amplifier with a phenomenal 5,500 V/µs slew rate that results in a rise time of 545 ps, making it ideal as a pulse amplifier.The high slew rate reduces the effect of slew rate limiting and results in the large signal bandwidth of 440 MHz required for high resolution video graphic systems. Signal quality is maintained over a wide bandwidth with worst case distortion of -40 dBc @ 250 MHz (G = +10, 1 V p-p). For applications with multitone signals such as IF signal chains, the third order Intercept (3IP) of 12 dBm is achieved at the same frequency. This distortion performance coupled with the current feedback architecture make the AD8009 a flexible component for a gain stage amplifier in IF/RF signal chains.The AD8009 is capable of delivering over 175 mA of load current and will drive four back terminated video loads while maintaining low differential gain and phase error of 0.02% & 0.04° respectively. The high drive capability is also reflected in the ability to deliver 10 dBm of output power @ 70 MHz with -38 dBc SFDR.The AD8009 is available in a small SOIC package and will operate over the industrial temperature range -40° C to +85° C. The AD8009 is also available in an SOT-23-5 and will operate over the commercial temperature range of 0°C to 70°C.An evaluation board is available for this product and may be ordered using the following product number: AD8009-EB.

The ADXRS453 is an angular rate sensor (gyroscope) intended for industrial, instrumentation, and stabilization applications in high vibration environments. An advanced, differential, quad sensor design rejects the influence of linear acceleration, enabling the ADXRS453 to offer high accuracy rate sensing in harsh envi-ronments where shock and vibration are present.The ADXRS453 uses an internal, continuous self-test architec-ture.
