The AD627 is an integrated, micropower instrumentation amplifier that delivers rail-to-rail output swing on single and dual (+2.2 V to ±18 V) supplies. The AD627 provides excellent ac and dc specifications while operating at only 85 μA maximum.The AD627 offers superior flexibility by allowing the user to set the gain of the device with a single external resistor while con-forming to the 8-lead industry-standard pinout configuration. With no external resistor, the AD627 is configured for a gain of 5. With an external resistor, it can be set to a gain of up to 1000.A wide supply voltage range (+2.2 V to ±18 V) and micropower current consumption make the AD627 a perfect fit for a wide range of applications. Single-supply operation, low power consumption, and rail-to-rail output swing make the AD627 ideal for battery-powered applications. Its rail-to-rail output stage maximizes dynamic range when operating from low supply voltages. Dual-supply operation (±15 V) and low power consumption make the AD627 ideal for industrial applications, including 4 to 20 mA loop-powered systems.The AD627 does not compromise performance, unlike other micropower instrumentation amplifiers. Low voltage offset, offset drift, gain error, and gain drift minimize errors in the system. The AD627 also minimizes errors over frequency by providing excellent CMRR over frequency. Because the CMRR remains high up to 200 Hz, line noise and line harmonics are rejected.The AD627 provides superior performance, uses less circuit board area, and costs less than micropower discrete designs.Applications4 mA to 20 mA loop-powered applicationsLow power medical instrumentation—ECG, EEGTransducer interfacingThermocouple amplifiersIndustrial process controlsLow power data acquisitionPortable battery-powered instruments

The AD640 is a complete monolithic logarithmic amplifier. A singleAD640 provides up to 50 dB of dynamic range for frequenciesfrom dc to 120 MHz. Two AD640s in cascade can provide up to95 dB of dynamic range at reduced bandwidth. The AD640 uses asuccessive detection scheme to provide an output current proportionalto the logarithm of the input voltage. It is laser calibrated toclose tolerances and maintains high accuracy over the full militarytemperature range using supply voltages from ±4.5 V to ±7.5 V.The AD640 comprises five cascaded dc-coupled amplifier/limiterstages, each having a small signal voltage gain of 10 dB and a –3 dBbandwidth of 350 MHz. Each stage has an associated full-wavedetector, whose output current depends on the absolute value of itsinput voltage. The five outputs are summed to provide the videooutput (when low-pass filtered) scaled at 1 mA per decade (50 µAper dB). On chip resistors can be used to convert this output currentto a voltage with several convenient slope options. A balancedsignal output at +50 dB (referred to input) is provided to operateAD640s in cascade.The logarithmic response is absolutely calibrated to within ±1 dBfor dc or square wave inputs from ±0.75 mV to ±200 mV, withan intercept (logarithmic offset) at 1 mV dc. An integral X10attenuator provides an alternative input range of ±7.5 mV to±2 V dc. Scaling is also guaranteed for sinusoidal inputs.The AD640B is specified for the industrial temperature range of–40°C to +85°C and the AD640T, available processed to MILSTD-883B,for the military range of –55°C to +125°C. Both areavailable in 20-lead side-brazed ceramic DIPs or leadless chipcarriers (LCC). The AD640J is specified for the commercialtemperature range of 0°C to +70°C, and is available in both20-lead plastic DIP (N) and PLCC (P) packages.This device is now available to Standard Military Drawing(DESC) number 5962-9095501MRA and 5962-9095501M2A.Product Highlights Absolute calibration of a wideband logarithmic amplifier is unique. The AD640 is a high accuracy measurement device, not simply a logarithmic building block. Advanced design results in unprecedented stability over the full military temperature range. The fully differential signal path greatly reduces the risk of instability due to inadequate power supply decoupling and shared ground connections, a serious problem with commonly used unbalanced designs. Differential interfaces also ensure that the appropriate ground connection can be chosen for each signal port. They further increase versatility and simplify applications. The signal input impedance is ~500 kΩ in shunt with ~2 pF. The dc-coupled signal path eliminates the need for numerous interstage coupling capacitors and simplifies logarithmic conversion of subsonic signals. The low input offset voltage of 50 µV (200 µV max) ensures good accuracy for low level dc inputs. Thermal recovery “tails,” which can obscure the response when a small signal immediately follows a high level input, have been minimized by special attention to design details. The noise spectral density of 2 nV/√Hz results in a noise floor of ~23 µV rms (–80 dBm) at a bandwidth of 100 MHz. The dynamic range using cascaded AD640s can be extended to 95 dB by the inclusion of a simple filter between the two devices.Applications Radar, sonar, ultrasonic and audio systems Precision instrumentation from DC to 120 MHz Power measurement with absolute calibration Wide range high accuracy signal compression Alternative to discrete and hybrid IF strips Replaces several discrete log amp ICs
