ADR2801.2 V Ultralow Power High PSRR Voltage Reference | Integrated Circuits (ICs) | 4 | Active | The ADR280 is a 1.2 V band gap core reference with excellent line regulation and power supply rejection designed specifically for applications experiencing heavy dynamic supply variations, such as data converter references in GSM, GPRS, and 3G mobile station applications. Devices such as the AD6535 that have an analog baseband IC with on-board baseband, audio codecs, voltage regulators, and battery chargers rely on the ability of the ADR280 to reject input battery voltage variations during RF power amplifier activity.In addition to mobile stations, the ADR280 is suitable for a variety of general-purpose applications. Most band gap references include internal gain for specific outputs, which simplifies the user’s design, but compromises on the cost, form factor, and flexibility. The ADR280, on the other hand, optimizes the band gap core voltage and allows users to tailor the voltage, current, or transient response by simply adding their preferred op amps.The ADR280 operates on a wide supply voltage range from 2.4 V to 5.5 V. It is available in compact 3-lead SOT-23 and SC70 packages. The device is specified over the extended industrial temperature range of −40°C to +85°C.APPLICATIONSList GSM, GPRS, 3G mobile stationsPortable battery-operated electronicsLow voltage converter referencesWireless devices |

ADR293Low Noise, Micropower 5.0 V Precision Voltage Reference | Integrated Circuits (ICs) | 13 | Active | The ADR293 is a low noise, micropower precision voltage reference that utilizes an XFET®(eXtra implanted junction FET) reference circuit. The XFET architecture offers significant performance improvements over traditional band gap and buried Zener-based references. Improvements include one quarter the voltage noise output of band gap references operating at the same current, very low and ultralinear temperature drift, low thermal hysteresis, and excellent long-term stability.The ADR293 is a series voltage reference providing stable and accurate output voltage from a 6.0 V supply. Quiescent current is only 15 μA maximum, making this device ideal for battery powered instrumentation. The temperature coefficient is 30 ppm/°C maximum over the military temperature range, and the initial error is only 0.2% at 25°C. Line regulation and load regulation are typically 70 ppm/V and 30 ppm/mA, respectively, maintaining the reference’s overall high performance.The ADR293 is specified over the military temperature range of –55°C to +125°C. This device is available in an 8-lead TSSOP package.The ADR293-EP support defense and aerospace applications (AQEC).APPLICATIONSPortable instrumentationPrecision reference for 5 V systemsADC and DAC referenceSolar-powered applications |
