The AD5673R/AD5677R are low power, 16-channel, 12-/16-bit, buffered voltage output, digital-to-analog converters (DACs) that include a 2.5 V, 2 ppm/?C internal reference (enabled by default), and a gain select pin, resulting in a full-scale output of 2.5 V (gain = 1) or 5 V (gain = 2). The devices operate from a single, 2.7 V to 5.5 V supply range and are guaranteed monotonic by design. The AD5673R/AD5677R are available in a 28-lead lead frame chip scale package (LFCSP) and incorporate a power-on reset (POR) circuit that ensures that the DAC outputs power up to and remain at zero scale or midscale until a valid write. The AD5673R/AD5677R contain a power-down mode that reduces the current consumption to 2 ?A typical.Applications Optical transceivers Base station power amplifiers Process control (programmable logic controller (PLC) input/output cards) Industrial automation Data acquisition systems Product Highlights High channel density: 16 channels in 4 mm ? 4 mm LFCSP. High relative accuracy (INL). AD5673R (12-bit): ?1 LSB maximum. AD5677R (16-bit): ?4 LSB maximum. Low drift, 2.5 V, on-chip reference.

The ADA4571-2 is a 2-channel anisotropic magneto resistive (AMR) sensor with integrated signal conditioning amplifiersand ADC drivers. The device produces analog outputs that indicate the angular position of the surrounding magnetic field.Each channel consists of two die within one package: an AMR sensor and a variable gain instrumentation amplifier. The ADA4571-2 delivers clean and amplified cosine and sine output signals per channel related to the angle of a rotating magnetic field. The output voltage range is ratiometric to the supply voltage.Each sensing channel contains two separated wheatstone bridges at a relative angle of 45? to one another. A rotating magnetic field parallel to the plane of the IC package delivers two sinusoidal output signals, with the double frequency of the angle, ?, between the sensor and the magnetic field direction. Within a homogeneous field parallel to the plane of the IC package, the output signals are independent of airgap between the sensor and the magnet.The ADA4571-2 is available in a 16-lead SOIC package.Product Highlights Contactless angular measurement. Measures magnetic field direction rather than field intensity. Minimum sensitivity to air gap variations. Large working distance. Excellent accuracy, even for weak saturation fields. Minimal thermal and lifetime drift. Negligible hysteresis.Single-chip solution.Applications Permanent magnet synchronous motor (PMSM) control and positioning Contactless angular measurement and detection?

Using the Scaler in the TVP5154
Texas Instruments
The TVP5154 video decoder product includes the additional functionality of an integrated polymorphic down-scaler for both vertical and horizontal scaling. The video images can be downscaled in both horizontal and vertical directions to an arbitrary size. This Application Note outlines how to correctly use this scaler feature for standard NTSC and PAL video. Also included are the register settings
