It generates a single-ended 50 ? output. The two versions offer input baseband bias levels of 500 mV (ADL5375-05) and 1500 mV (ADL5375-15).The ADL5375 is fabricated using an advanced silicon-germanium bipolar process. It is available in a 24-lead, exposed paddle, Pb-free, LFCSP_VQ package. Performance is specified over a ?40?C to +85?C temperature range.

Extremely high-speed ADCs (>1 GSPS) demand a low-jitter sample clock in order to preserve signal-tonoiseratio (SNR). These 8- and 10-bit converters have best-case noise floors set by quantization noise.For an N-bit ADC sampling a full-scale sinusoid the well known expression for SNR (in dB) is: SNR =6.02N + 1.76. This sets the best case noise floor for an 8-bit ADC at −49.9 dBc. The noise f

The PMP3866 reference design is a dual synchronous buck that uses the TPS40140 to generate 5V@5A and 3.3V@5A. The input voltage range is 18V to 30V. This design is used in a hard drive tester application. The two power supplies operate 180 degrees out of phase with each other to reduce the input

PMP2844 uses two UCC2897s to generate two isolated outputs from 36V – 72V. The 3.3V at 20A converter uses an active clamp forward topology with synchronous rectifiers. The 15V at 1.5A converter uses a flyback topology. Both converters are operating at 200KHz to keep the efficiency high.

This reference design provides reinforced isolated positive and negative voltage rails required for Insulated Gate Bipolar Transistor (IGBT) gate drivers from a single 24-volt DC input supply. Utilizing a flyback isolated control topology: this reference design provides isolation compliant to IEC61800-5: and generates power rails for all three arms of the 3-phase inverter from a single transformer. The output power is currently set at 2W/IGBT but can be scaled up for higher power IGBTs by changing the transformer design.

The AD8556 is a zero-drift, sensor signal amplifier withdigitally programmable gain and output offset. Designed toeasily and accurately convert variable pressure sensor andstrain bridge outputsto a well-defined output voltage range,the AD8556 accurately amplifies many other differential orsingle-ended sensor outputs. The AD8556 uses the ADIpatented low noise auto-zero and DigiTrim? technologies tocreate an incredibly accurate and flexible signal processingsolution in a very compact footprint.Gain is digitally programmable in a wide range from 70 to1,280 through a serial data interface. Gain adjustment canbe fully simulated in-circuit and then permanently programmedwith reliable polyfuse technology. Output offsetvoltage is also digitally programmable and is ratiometric to thesupply voltage. AD8556 also features internal EMI filters on theVNEG, VPOS, FILT and VCLAMP pins.In addition to extremely low input offset voltage, low inputoffset voltage drift, and very high dc and ac CMRR, the AD8556 also includes a pull-up current source at the input pinsand a pull-down current source at the VCLAMP pin. Thisallows open wire and shorted wire fault detection. A low-passfilter function is implemented via a single low cost externalcapacitor. Output clamping set via an external reference voltageallows the AD8556 to drive lower voltage ADCs safely andaccurately.When used in conjunction with an ADC referenced to the samesupply, the system accuracy becomes immune to normal supplyvoltage variations. Output offset voltage can be adjusted with aresolution of better than 0.4% of the difference between VDDand VSS. A lockout trim after gain and offset adjustmentfurther ensures field reliability.The AD8556 is fully specified from ?40?C to +140?C.Operating from single-supply voltages of 2.7 V to 5.5 V, theAD8556 is offered in the 8-lead SOIC_N, and 4 mm ? 4 mm16-lead LFCSP_VQ.ApplicationsAutomotive SensorsPressure and Position SensorsPrecision Current SensingStrain Gages

The AD8334 is an ultralow noise, quad channel linear-in-dB variable gain amplifier (VGA). Although optimized for ultrasound systems, it may be used as a low noise variable gain control in any application whose operating frequency is less than 100 MHz.Included in each channel are an ultralow noise preamp (LNA), an X-AMP? VGA with 48 dB of gain range, and a selectable gain postamp with adjustable output limiting. The LNA gain is 19 dB with a single-ended input and differential outputs. Using a single resistor, the LNA input impedance can be adjusted to match a signal source without compromising noise performance.The 48 dB gain range of the VGA makes these devices suitable for a variety of applications. Excellent bandwidth uniformity is maintained across the entire range. The gain control interface provides precise linear-in-dB scaling of 50 dB/V for control voltages between 40 mV and 1 V. Factory trim ensures excellent part-to-part and channel-to-channel gain matching. Differential signal paths result in superb second- and third-order distortion performance and low crosstalk.The AD8334 is a quad version of the single AD8331 and dual AD8332.For information on specs, see the AD8331/AD8332/AD8334 datasheet.Applications Ultrasound and sonar time-gain controls High performance automatic gain control (AGC) systems I/Q signal processing High speed, dual ADC drivers
