It has been developed specifically with the 5V Dual power supply 2.5V to 5.0V operation single supply or 2.5 dual supply user in mind and offers the industry Single power supply +5V to +10V operation pin configuration of A741 and ICL7611 types. High voltage gain -- typically 85V/mV 2.5V and 250V/mV 5.0V Several important characteristics of the device make many applications Drive as low as 2K load with 5mA easy to implement for these supply voltages. First, the operational drive current amplifier can operate with rail to rail input and output voltages. This Output short circuit protected feature allows numerous analog serial stages to be implemented without Unity gain bandwidth of 1.5MHz (1MHz min.) losing operating voltage margin. Second, the device was designed to Slew rate of 2.1V/s (1.4V/s min.) accommodate mixed applications where digital and analog circuits may Low power dissipation work off the same 5V power supply. Third, the output stage can drive Suitable for rugged, temperature-extreme up to 400pF capacitive and 5K resistive loads in non-inverting unity environments gain connection and double the capacitance in the inverting unity gain mode. APPLICATIONS Voltage amplifier These features, coupled with extremely low input currents, high voltage Voltage follower/buffer gain, useful bandwidth of 1.5MHz, slew rate of 2.1V/s, low power Charge integrator dissipation, low offset voltage and temperature drift, make the ALD1702A/ Photodiode amplifier ALD1702B/ALD1702/ALD1703 a truly versatile, user friendly, operational Data acquisition systems amplifier. High performance portable instruments The ALD1702A/ALD1702B/ALD1702/ALD1703 is designed and Signal conditioning circuits fabricated with silicon gate CMOS technology, and offers 1pA typical Sensor and transducer amplifiers input bias current. On-chip offset voltage trimming allows the device to Low leakage amplifiers be used without nulling in most applications. The device offers typical Active filters offset drift of less than 7V/C which eliminates many trim or temperature Sample/Hold amplifier compensation circuits. For precision applications, it is designed to settle Picoammeter to 0.01% in 8s. Additionally, robust design and rigorous screening make Current to voltage converter this device especially suitable for operation in temperature-extreme Coaxial cable driver environments and rugged conditions.
