The AD7732 is a high precision, high throughput analog front end. True 16-bit peak-to-peak resolution is achievable with total conversion times of 500 ?s (2 kHz channel switching) making it ideally suitable for high resolution multiplexing applications.The part can be configured via a simple digital interface, which allows users to balance the noise performance against data throughput up to a 15.4 kHz.The analog front end features two fully differential input channels with unipolar or true bipolar input ranges to ?10 V while operating from a single +5 V analog supply. The part has an overrange and underrange detection capability and accepts an analog input overvoltage to ?16.5 V without degrading the performance of the adjacent channels.The differential reference input features ?No-Reference? detect capability. The ADC also supports per channel system calibration options. The digital serial interface can be configured for 3-wire operation and is compatible with microcontrollers and digital signal processors. All interface inputs are Schmitt triggered. The part is specified for operation over the extended industrial temperature range of ?40?C to +105?C and is available in 28-lead TSSOP package.Other parts in the AD7732 family are the AD7734?and the AD7738.The AD7734 is similar to AD7732, but its analog front end features four single-ended input channels.The AD7738 analog front end is configurable for four fully differential or eight single-ended input channels, features 0.625 V to 2.5 V bipolar/unipolar input ranges, and accepts a common-mode input voltage from 200 mV to AVDD ? 300 mV. The AD7738 multiplexer output is pinned out externally, allowing the user to implement programmable gain or signal conditioning before being applied to the ADC.APPLICATIONS PLCs/DCS Multiplexing applications Process control Industrial instrumentation

The ADM2484E is an isolated data transceiver with ?15 kVESD protection suitable for high speed, half- or full-duplex communication on multipoint transmission lines. For half-duplex operation, the transmitter outputs and receiver inputs share the same transmission line. Transmitter Output Pin Y links externally to Receiver Input Pin A, and Transmitter Output Pin Z links externally to Receiver Input Pin B.Designed for balanced transmission lines, the ADM2484Ecomplies with ANSI TIA/EIA RS-485-A-1998 and ISO 8482: 1987(E). The device employs Analog Devices, Inc., iCoupler? technology to combine a 3-channel isolator, a three-state differential line driver, and a differential input receiver into a single package.The differential transmitter outputs and receiver inputs featureelectrostatic discharge circuitry that provides protection up to ?15 kV using the human body model (HBM). The logic side of the device can be powered with either a 5 V or a 3.3 V supply, whereas the bus side requires an isolated 3.3 V supply.The device has current-limiting and thermal shutdown featuresto protect against output short circuits and situations where buscontention causes excessive power dissipation.Applications Isolated RS-485/RS-422 interfaces Industrial field networks INTERBUS Multipoint data transmission systems

Demonstration circuit 2365A highlights the LTC2358 family of buffered input ADCs. The LTC2358/LTC2357/LTC2353/LTC2333 are low noise, high speed, 16-/18-bit successive approximation register (SAR) ADCs with integrated front end buffers. These ADCs accept a wide common mode range. Pico-amp inputs and high CMRR enable these ADCs to connect directly to a wide range of sensors without compromising measurement accuracy. The demo manual refers to the LTC2358-18 but applies to all parts in the family, the only differences being the number of bits, number of channels and the maximum sample rate. The LTC2358-18 has a flexible SoftSpan™ interface that allows conversion-by-conversion control of the input voltage span on a per-channel basis. An internal 2.048V reference and 2X buffer simplify basic operation while an external reference can be used to increase the input range and the SNR of the ADC.
