High slew rate operational amplifier
NE/SE531
DESCRIPTION
The 531 is a fast slewing high performance operational amplifier which retains DC performance equal to the best general purpose types while providing far superior large-signal AC performance. A unique input stage design allows the amplifier to have a large-signal response nearly identical to its small-signal response. The amplifier is compensated for truly negligible overshoot with a single capacitor. In applications where fast settling and superior large-signal bandwidths are required, the amplifier out-performs conventional designs which have much better small-signal response. Also, because the small-signal response is not extended, no special precautions need be taken with circuit board layout to achieve stability. The high gain, simple compensation, and excellent stability of this amplifier allow its use in a wide variety of instrumentation applications.

CYCLIC A-TO-D CONVERTER
One interesting, but much ignored, A/D converter is the cyclic converter. This consists of a chain of identical stages, each of which senses the polarity of the input. The stage then subtracts VREF from the input and doubles the remainder if the polarity was correct. In Figure 1, the signal is full-wave rectified and the remainder of VIN-VREF is doubled. A chain of these stages gives the gray code equivalent of the input voltage in digitized form related to the magnitude of VREF. Possessing high potential accuracy, the circuit using NE531 devices settles in 5s.
swing of op amp A-1, and R1/R2 sets the triangle amplitude. The frequency of oscillation in either case is: f+ 1 R2 @ 4RC R1 (1)
The square wave will maintain 50% duty cycle even if the amplitude of the oscillation is not symmetrical. The use of the NE531 in this circuit will allow good square waves to be generated to quite high frequencies. Since the amplifier A1 runs open-loop, there is no need for compensation. The triangle-generating amplifier must be compensated. The NE5535 device can be used as well, except for the lower frequency response.
TRIANGLE AND SQUARE WAVE GENERATOR
The circuit in Figure 2 will generate precision triangle and square waves. The output amplitude of the square wave is set by the output
