The AD7730L is a complete analog front end for weigh-scale and pressure measurement applications. The device accepts low-level signals directly from a transducer and outputs a serial digital word. Theinput signal is applied to a proprietary programmable gain front end based around an analog modulator. The modulator output is processed by a low pass programmable digital filter, allowing adjustment of filter cutoff, output rate and settling time.The part features two buffered differential programmable gain analog inputs as well as a differential reference input. The device operates from a single +5 V supply. It accepts four unipolar analog input ranges: 0 mV to +10 mV, +20 mV, +40 mV and +80 mV and four bipolar ranges: ±10 mV, ±20 mV, ±40 mV and ±80 mV. The peak-to-peak resolution achievable directly from the part is 1 in 110,000 counts. An on-chip 6-bit DAC allows the removal of TARE voltages. Clock signals for synchronizing ac excitation of the bridge are also provided.The serial interface on the part can be configured for three-wire operation and is compatible with microcontrollers and digital signal processors. The AD7730L contains self-calibration and system calibration options, and features an offset drift of less than 5 nV/°C and a gain drift of less than 3 ppm/°C. The part is available in a 24-lead SOIC and 24-lead TSSOP package. It is a lower power version of the AD7730 (approximately 1/3 the power).

The ADCMP563/ADCMP564 are high speed comparatorsfabricated on Analog Devices’ proprietary XFCB process. Thedevices feature a 700 ps propagation delay with less than 75 psoverdrive dispersion. Dispersion, a measure of the difference inpropagation delay under differing overdrive conditions, is a particularlyimportant characteristic of high speed comparators. A separateprogrammable hysteresis pin is available on the ADCMP564.A differential input stage permits consistent propagation delaywith a wide variety of signals in the common-mode range from−2.0 V to +3.0 V. Outputs are complementary digital signals thatare fully compatible with ECL 10 K and 10 KH logic families.The outputs provide sufficient drive current to directly drivetransmission lines terminated in 50 Ω to −2 V. A latch input,which is included, permits tracking, track-and-hold, or sample-and-holdmodes of operation. The latch input pins contain internalpull-ups that set the latch in tracking mode when left open.The ADCMP563/ADCMP564 are specified over the industrialtemperature range (−40°C to +85°C).Applications Automatic test equipment High speed instrumentation Scope and logic analyzer front ends Window comparators High speed line receivers Threshold detection Peak detection High speed triggers Patient diagnostics Hand-held test instruments Zero crossing detectors Line receivers and signal restoration Clock drivers
