... CMOS designs have been achieved. Both input and output ranges include the negative supply, providing the user with zero-in/zero-out capability. For users of 3.3 V systems such as lithium batteries, the OP295/OP495 are specified for 3 V operation. Maximum offset voltage is specified at 300 μV for 5 V operation, and the open-loop gain is a minimum of 1000 V/mV ...

... Closed-Loop Gain 1000 DRIVING HEAVY LOADS The OP295/OP495 are well suited to drive loads by using a power transistor, Darlington, or FET to increase the current to the load. The ability to swing to either rail can assure that the device is turned on hard. This results in more power to the load and an increase in efficiency over using standard op amps with their limited output swing ...

... V. SINGLE-SUPPLY RTD THERMOMETER AMPLIFIER This RTD amplifier takes advantage of the rail-to-rail swing of the OP295/OP495 to achieve a high bridge voltage in spite of a low 5 V supply. The OP295/OP495 amplifier servos a constant 200 μA current to the bridge. The return current drops across the parallel resistors 6.19 kΩ and 2.55 MΩ, developing a voltage that is servoed to 1 ...

... Figure 28 shows a simple 3 V voltage regulator design. The regulator can deliver 50 mA load current while allowing a 0.2 V dropout voltage. The OP295/OP495 rail-to-rail output swing drives the MJE350 pass transistor without requiring special drive circuitry load, its output can swing less than the pass transistor’ ...
