AD706JRZ

Analog Devices Inc.
The AD706 is a dual, low power, bipolar op amp that has thelow input bias current of a JFET amplifier, but which offers asignificantly lower IB drift over temperature. It utilizes superbetabipolar input transistors to achieve picoampere input bias currentlevels (similar to FET input amplifiers at room temperature),while its IB typically only increases by 5 at 125°C (unlike aJFET amp, for which IB doubles every 10°C for a 1000×increase at 125°C). The AD706 also achieves the microvoltoffset voltage and low noise characteristics of a precision bipolarinput amplifier.Since it has < 200 pA of bias current, the AD706 does notrequire the commonly used “balancing” resistor. Furthermore,the current noise is only 50 fA/√Hz, which makes this amplifierusable with very high source impedances. At 600 A max supplycurrent (per amplifier), the AD706 is well suited for today’shigh density boards.The AD706 is an excellent choice for use in low frequencyactive filters in 12-bit and 14-bit data acquisition systems, inprecision instrumentation, and as a high quality integrator. TheAD706 is internally compensated for unity gain and is availablein five performance grades. The AD706J is rated over thecommercial temperature range of 0°C to +70°C. The AD706A israted for the extended industrial temperature range of −40°Cto +85°C.The AD706 is offered in two varieties of an 8-lead package:PDIP and surface-mount (SOIC).PRODUCT HIGHLIGHTS The AD706 is a dual low drift op amp that offers JFET level input bias currents, yet has the low IB drift of a bipolar amplifier. It may be used in circuits using dual op amps such as the LT1024. The AD706 provides both low drift and high dc precision. The AD706 can be used in applications where a chopper amplifier would normally be required but without the chopper’s inherent noise.APPLICATIONS Low Frequency Active Filters Precision Instrumentation Precision Integrators

AD7233BNZ

Analog Devices Inc.
The AD7233 is a complete 12-bit, voltage-output, digital-to-analog converter with output amplifier and Zener voltage reference all in an 8-pin package. No external trims are required to achieve full specified performance. The data format is 2s complement, and the output range is -5V to +5V.The AD7233 features a fast, versatile serial interface which allows easy connection to both microcomputers and 16-bit digital signal processors with serial ports. When the SYNC input is taken low, data on the SDIN pin is clocked into the input shift register on each falling edge of SCLK. On completion of the 16-bit data transfer, bringing LDAC low updates the DAC latch with the lower 12 bits of data and updates the output. Alternatively, LDAC can be tied permanently low, and in this case the DAC register is automatically updated with the contents of the shift register when all sixteen data bits have been clocked in. The serial data may be applied at rates up to 5 MHz allowing a DAC update rate of 300 kHz.For applications which require greater flexibility and unipolar output ranges with single supply operation, please refer to the AD7243 data sheet.The AD7233 is fabricated on Linear Compatible CMOS (LC2MOS), an advanced, mixed-technology process. It is packaged in an 8-pin DIP package.
