The AD625 is a precision instrumentation amplifier specifically designed to fulfill two major areas of application: 1) Circuits requiring nonstandard gains (i.e., gains not easily achievable with devices such as the AD524 and AD624). 2) Circuits requiring a low cost, precision software programmable gain amplifier.For low noise, high CMRR, and low drift the AD625JN is the most cost effective instrumentation amplifier solution available. An additional three resistors allow the user to set any gain from 1 to 10,000. The error contribution of the AD625JN is less than 0.05% gain error and under 5 ppm/°C gain TC; performance limitations are primarily determined by the external resistors. Common-mode rejection is independent of the feedback resistor matching.A software programmable gain amplifier (SPGA) can be configured with the addition of a CMOS multiplexer (or other switch network), and a suitable resistor network. Because the ON resistance of the switches is removed from the signal path, an AD625 based SPGA will deliver 12-bit precision, and can be programmed for any set of gains between 1 and 10,000, with completely user selected gain steps.For the highest precision the AD625C offers an input offset voltage drift of less than 0.25 µV/°C, output offset drift below 15 µV/°C, and a maximum nonlinearity of 0.001% at G = 1. All grades exhibit excellent ac performance; a 25 MHz gain bandwidth product, 5 V/µs slew rate and 15 µs settling time.The AD625 is available in three accuracy grades (A, B, C) for industrial (-40°C to +85°C) temperature range, two grades (J, K) for commercial (0°C to +70°C) temperature range, and one (S) grade rated over the extended (-55°C to +125°C) temperature range.

The AD704 is a quad, low power bipolar op amp that has the low input bias current of a BiFET amplifier and offers a significantly lower IB drift over temperature. It uses superbeta bipolar input transistors to achieve picoampere input bias current levels (similar to FET input amplifiers at room temperature), while its IB typically increases only by 5× at 125°C (unlike a BiFET amp, for which IB doubles every 10°C, resulting in a 1000× increase at 125°C). In addition, the AD704 achieves 150 μV offset voltage and the low noise characteristics of a precision bipolar input op amp.Because it has only 1/20 the input bias current of an OP07, the AD704 does not require the commonly used balancing resistor. Furthermore, the current noise is 1/5 that of the OP07, which makes the AD704 usable with much higher source impedances. At 1/6 the supply current (per amplifier) of the OP07, the AD704 is better suited for today’s higher density circuit boards and battery-powered applications.The AD704 is an excellent choice for use in low frequency active filters in 12- and 14-bit data acquisition systems, in precision instrumentation, and as a high quality integrator. The AD704 is internally compensated for unity gain stability. The AD704J is rated over the commercial temperature range of 0°C to 70°C. The AD704A is rated over the industrial temperature of −40°C to +85°C. The AD704S is rated over the military temperature range of −55°C to +125°C, processed to MIL-STD-883B.APPLICATIONS Industrial/process controls Weigh scales ECG/EKG instrumentation Low frequency active filters

It offers the excellent dc characteristics of the AD711 BiFET family with enhanced settling, slew rate, and bandwidth. The AD744 also offers the option of using custom compensation to achieve exceptional capacitive load drive capability.The single-pole response of the AD744 provides fast settling: 500 ns to 0.01%.

External compensation may be applied to the AD744 for stable operation as a unity gain follower. External compensation also allows the AD744 to drive 1000 pF capacitive loads, slewing at 10 V/µs with full stability.Alternatively, external decompensation may be used to increase the gain bandwidth of the AD744 to over 200 MHz at high gains. This makes the AD744 ideal for use as ac preamps in digital signal processing (DSP) front ends.The AD744 is available in seven performance grades.

The AD790 is a fast (45 ns), precise voltage comparator, with a number of features that make it exceptionally versatile and easy to use. The AD790 may operate from either a single +5 V supply or a dual ±15 V supply. In the single-supply mode, the AD790's inputs maybe referred to ground, a feature not found in other comparators. In the dual-supply mode it has the unique ability of handling a maximum differential voltage of 15 V across its input terminals, easing their interfacing to large amplitude and dynamic signals.The device is fabricated using Analog Devices' Complementary Bipolar (CB) process - which gives the AD790's combination of fast response time and outstanding input voltage resolution (1mV max). To preserve its speed and accuracy, the AD790 incorporates a 'low glitch' output stage that does not exhibit the large current spikes normally found in TTL or CMOS output stages. Its controlled switching reduces power supply disturbances that can feed back to the input and cause undesired oscillations. The AD790 also has a latching function which makes it suitable for applications requiring synchronous operation.The AD790 is available in five performance grades. The AD790J and the AD790K are rated over the commercial temperature range of 0°C to 70°C. The AD790a and AD790B are rated over the industrial temperature range of −40°C to +85°C. The AD790S is rated over the military temperature range of −55°C to +125°C and is available to MIL-STD-883B, Rev. C.PRODUCT HIGHLIGHTS The AD790’s combination of speed, precision, versatility and low cost makes it suitable as a general purpose comparator in analog signal processing and data acquisition systems. Built-in hysteresis and a low-glitch output stage minimize the chance of unwanted oscillations, making the AD790 easier to use than standard open-loop comparators. The hysteresis combined with a wide input voltage range enables the AD790 to respond to both slow, low level (e.g., 10 mV) signals and fast, large amplitude (e.g., 10 V) signals. A wide variety of supply voltages is acceptable for operation of the AD790, ranging from single 5 V to dual +5 V/–12 V, ±5 V, or +5 V/±15 V supplies. The AD790’s power dissipation is the lowest of any comparator in its speed range. The AD790’s output swing is symmetric between VLOGIC and ground, thus providing a predictable output under a wide range of input and output conditions.APPLICATIONS Zero-Crossing Detectors Overvoltage Detectors Pulse-Width Modulators Precision Rectifiers Discrete A/D Converters Delta-Sigma Modulator A/Ds
