| TLC2201 The OPA2680 represents a major step forward in unity gain stable, voltage feedback op amps. A new internal architecture provides slew rate and full power bandwidth previously found only in wideband current feedback op amps. A new output stage architecture delivers high currents with a minimal headroom requirement.
These combine to give exceptional single supply operation.
Using a single +5V supply, the OPA2680 can deliver a 1V to 4V output swing with over 100mA drive current and 150MHz bandwidth. This combination of features makes the OPA2680 an ideal RGB line driver or single supply ADC input driver.
The OPA2680’s low 6.4mA/ch. supply current is precisely trimmed at 25°C. This trim, along with low temperature drift, guarantees lower maximum supply current than competing products. System power may be reduced further using the optional disable control pin (SO-14 package only). Leaving this disable pin open, or holding it high, will operate the OPA2680N normally. If pulled low, the OPA2680N supply current drops to less than 600μA while the output goes into a high impedance state. ...
TLC2201 The AD8316 is a complete, low cost subsystem for the precise control of dual RF power amplifiers (PAs) operating in the frequency range 0.1 GHz to 2.5 GHz and over a typical dynamic range of 50 dB. The device is a dual-output version of the AD8315 and intended for use in dual-band or triband cellular hand sets and other battery-operated wireless devices where a separatepower control signal is required for each band. The logarithmic amplifier technique provides a much wider measurement range and better accuracy than is possible using controllers based on diode detectors. In particular, multiband and multimode cellu-lar designs can benefit from the temperature-stable (–30°C to+85°C) operation over all cellular telephony frequencies.
Its high sensitivity allows control at low input signal levels, thusreducing the amount of power that needs to be coupled to thedetector. The selected output, OUT1 or OUT2, has the voltage range and current drive to directly connect to the gain control pin of most handset power amplifiers; the deselected output is pulled low to ensure that the inactive PA remains off. Each output has a dedicated integrating filter capacitor that allows separate control loop settings for each PA. OUT1 and OUT2 can swing from 125 mV above ground to within 100 mV below the supply voltage. Load currents of up to 12 mA can be supported. The setpoint control input applied to pin VSET has an operating range of 0.25 V to 1.4 V. The input resistance of the setpoint Interface is over 100 M Ω, and the bias current is typically 0.5 µA.The AD8316 is available in 10-lead MSOP and 16-leadLFCSP packagesandconsumes 8.5 mA from a 2.7 V to 5.5 V supply.When it is powered down, the sleep current is 4 µA. ...
TLC2201 The DS90LV031A is a quad CMOS differential line driver designed for applications requiring ultra low power dissipation and high data rates. The device is designed to support data rates in excess of 400 Mbps (200 MHz) utilizing Low Voltage Differential Signaling (LVDS) technology.
The DS90LV031A accepts low voltage TTL/CMOS input levels and translates them to low voltage (350 mV) differential output signals. In addition the driver supports a TRI-STATE® function that may be used to disable the output stage, disabling the load current, and thus dropping the device to an ultra low idle power state of 13 mW typical.
The EN and EN* inputs allow active Low or active High control of the TRI-STATE outputs. The enables are common to all four drivers. The DS90LV031A and companion line receiver (DS90LV032A) provide a new alternative to high power psuedo-ECL devices for high speed point-to-point interface applications.
