Single Supply Quad Operational Amplifiers

The AD8275 is a G=0.2 difference amplifier that can be used to translate +/-10V signals to a +4V level. It solves the problem typically encountered in industrial and instrumentation where +/-10V signals must be interfaced to a single supply 4V or 5V ADC. The AD8275 interfaces the two signal levels, simplifying design. The AD8275 has fast settling time of 450 ns and low distortion, making it suitable for driving medium speed successive approximation (SAR) ADCs. Its wide input voltage range and rail-torail outputs make it an easy to use building block. Single-supply operation reduces the power consumption of the amplifier and helps to protect the ADC from overdrive conditions. Internal, matched, precision laser-trimmed resistors ensure low gain error, low gain drift of 1 ppm/°C (maximum), and high common-mode rejection of 80 dB. Low offset and low offset drift, combined with its fast settling time, make the AD8275 suitable for a variety of data acquisition applications where accurate and quick capture is required. The AD8275 can be used as an analog front end, or it can follow buffers to level translate high voltages to a voltage range accepted by the ADC. In addition, the AD8275 can be configured for differential outputs if used with a differential ADC. The AD8275 is available in a space-saving, 8-lead MSOP and is specified for performance over the ?40°C to +85°C temperature range.

Single Low Noise Operational Amplifier

The AD549 is a monolithic electrometer operational amplifier with very low input bias current. Input offset voltage and input offset voltage drift are laser trimmed for precision performance. The ultralow input current of the part is achieved with Topgate? JFET technology, a process development exclusive to Analog Devices, Inc. This technology allows fabrication of extremely low input current JFETs compatible with a standard junction isolated bipolar process. The 1015 ? common-mode impedance, which results from the bootstrapped input stage, ensures that the input current is essentially independent of the common-mode voltage. The AD549 is suited for applications that require very low input current and low input offset voltage. It excels as a preamp for a wide variety of current output transducers, such as photo-diodes, photomultiplier tubes, or oxygen sensors. The AD549 can also be used as a precision integrator or low droop sample and hold. The AD549 is pin compatible with standard FET and electrometer op amps, allowing designers to upgrade the performance of present systems at little additional cost. The AD549 is available in a TO-99 hermetic package. The case is connected to Pin 8 so that the metal case can be independently connected to a point at the same potential as the input terminals, minimizing stray leakage to the case. The AD549 is available in four performance grades. The J, K, and L versions are rated over the commercial temperature range of 0°C to +70°C. The S grade is specified over the military temperature range of ?55°C to +125°C and is available processed to MIL-STD-883B, Rev. C. Extended reliability plus screening is also available. Plus screening includes 168 hour burn-in, as well as other environmental and physical tests derived from MIL-STD-883B, Rev. C. Product Highlights The AD549 input currents are specified, 100% tested, and guaranteed after the device is warmed up. They are guaranteed over the entire common-mode input voltage range. The AD549 input offset voltage and drift are laser trimmed to 0.50 mV and 15 μV/°C (AD549K), and to 1 mV and 20 μV/°C (AD549J).. A maximum quiescent supply current of 700 μA minimizes heating effects on input current and offset voltage. AC specifications include 1 MHz unity gain bandwidth and 3 V/μs slew rate. Settling time for a 10 V input step is 5 μs to 0.01%. Applications Electrometer amplifier Photodiode preamp pH electrode buffer
