The AD8421 is a low cost, low power, extremely low noise, ultralow bias current, high speed instrumentation amplifier that is ideally suited for a broad spectrum of signal conditioning and data acquisition applications. This product features extremely high CMRR, allowing it to extract low level signals in the presence of high frequency common-mode noise over a wide temperature range. The 10 MHz bandwidth, 35 V/µs slew rate, and 0.6 µs settling time to 0.001% (G = 10) allow the AD8421 to amplify high speed signals and excel in applications that require high channel count, multiplexed systems. Even at higher gains, the current feedback architecture maintains high performance; for example, at G = 100, the bandwidth is 2 MHz and the settling time is 0.8 µs. The AD8421 has excellent distortion performance, making it suitable for use in demanding applications such as vibration analysis. The AD8421 delivers industry-leading 3 nV/√Hz input voltage noise and 200 fA/√Hz current noise with only 2 mA quiescent current, making it an ideal choice for measuring low level signals. For applications with high source impedance, the AD8421 employs innovative process technology and design techniques to provide noise performance that is limited only by the sensor. The AD8421 uses unique protection methods to ensure robust inputs while still maintaining very low noise. This protection allows input voltages up to 40 V from the opposite supply rail without damage to the part. A single resistor sets gains between 1 and 10,000. The reference pin can be used to apply a precise offset to the output voltage.The AD8421 performance is specified from −40°C to +85°C for the 8-lead MSOP and SOIC packages, and from −40°C to 125°C for the 8-lead LFCSP package.Applications Medical instrumentation Precision data acquisition Microphone preamplification Vibration analysis Multiplexed input applications ADC driver

The ADM1191 is an integrated current sense amplifier that offers digital current and voltage monitoring via an on-chip, 12-bit analog-to-digital converter (ADC), communicated through an I2C interface. An internal current sense amplifier senses voltage across the sense resistor in the power path via the VCC pin and the SENSE pin.A 12-bit ADC can measure the current seen in the sense resistor, as well as the supply voltage on the VCC pin.An industry-standard I2C interface allows a controller to read current and voltage data from the ADC. Measurements can be initiated by an I2C command or via the convert (CONV) pin. The CONV pin is especially useful for synchronizing reads on multiple ADM1191 devices. Alternatively, the ADC can run continuously, and the user can read the latest conversion data whenever it is required. Up to 16 unique I2C addresses can be created, depending on the way the A0 pin and the A1 pin are connected.A SETV pin is also included. A voltage applied to this pin is internally compared to the output voltage on the current sense amplifier. The output of the SETV comparator asserts when the current sense amplifier output exceeds the SETV voltage. When this event occurs, the ALERTB output asserts.The ALERTB output can be used as a flag to warn a micro-controller or field programmable gate array (FPGA) of an overcurrent condition. ALERTB outputs of multiple ADM1191 devices can be tied together and used as a combined alert.The ADM1191 is packaged in a 10-lead MSOP.APPLICATIONS Power monitoring/power budgeting Central office equipment Telecommunication and data communication equipment PCs/servers

The AD8129/AD8130 are designed as receivers for the transmission of high speed signals over twisted-pair cables to work with the AD8131 or AD8132 drivers. Either can be used for analog or digital video signals and for high speed data transmission. The AD8129/AD8130 are differential-to-single-ended amplifiers with extremely high CMRR at high frequency. Therefore, they canalso be effectively used as high speed instrumentation amps or for converting differential signals to single-ended signals.The AD8129 is a low noise, high gain (10 or greater) version intended for applications over very long cables, where signal attenuation is significant. The AD8130 is stable at a gain of 1 and can be used for applications where lower gains are required. Both have user-adjustable gain to help compensate for losses in the transmission line. The gain is set by the ratio of two resistor values. The AD8129/AD8130 have very high input impedance on both inputs, regardless of the gain setting. The AD8129/AD8130 have excellent common-mode rejection (70 dB @ 10 MHz), allowing the use of low cost, unshielded twisted-pair cables without fear of corruption by external noise sources or crosstalk. The AD8129/AD8130 have a wide power supply range from single +5 V to ±12 V, allowing wide common-mode and differential-mode voltage ranges while maintaining signal integrity. The wide common-mode voltage range enables the driver-receiver pair to operate without isolation transformers in many systems where the ground potential difference between drive and receive locations is many volts. The AD8129/AD8130 have considerable cost and performance improvements over op amps and other multiamplifier receiving solutions.
