Limiting Amplifier is Digitally Programmable:    06/04/98 EDN-Design Ideas / (added 11/05)  Amplitude limiters are necessary in many systems, such as radar and FM receivers, for which the system cannot allow the amplitude of the signal to exceed the given positive, negative, or both limits. In the circuit in Figure 1, amplifier IC4B's maximum output is digitally programmable over ±2 to ±10V in 2n steps, where n is the number of bits of the DAC. IC1, a precision 10V reference, provides a full-scale reference current, IREF=VREF/R1=2 mA, to IC2, a multiplying DAC. IC3's output voltage, VL, is the sum of the product of the digital word and unipolar...

Limiting Amplifier Makes Efficient A/D Converter Driver:    09/02/96 EDN-Design Ideas / (added 11.05)  Limiting amplifiers are useful for protecting circuitry that has a limited input range. A classic example is an input buffer for an A/D converter. Many A/D converters are susceptible to damage if the input significantly exceeds the specified range. In addition to providing the necessary input-voltage clamping, a limiting amplifier can provide the peak currents required to charge the A/D converter's input capacitance and remain stable with step changes in input voltage. The limiting amplifier also provides the gain and level-shifting frequently required at the front end of an A/D converter....
