Replacing Output Clamping Op Amps with Input Clamping Amps:  AN-402 Analog Devices Application Notes  (app note added 2/06) So far most clamping amplifiers have relied upon an output clamping architecture and are called output clamp amps (OCAs) . A new architecture called an input clamp amp (ICA)  offers superior clamping accuracy and lower distortion.

Single IC Provides Gains of 10 And10 :  08/07/03  EDN-Design Ideas / (added 10/03) Real-world data-acquisition systems require amplifying weak signals to match the full-scale input range of an A/D converter. Unfortunately, when you configure them as gain blocks, most common amplifiers have both gain errors and offset drift. The typical two-resistor gain-setting arrangement found in many op-amp circuits has serious accuracy and drift limitations....

Variable Gain Stage uses Voltage Output Dac:  08/01/97 EDN-Design Ideas / (added 4/02) A voltage-output DAC normally generates an output voltage that is a fraction of the input-reference voltage. In many designs, however, it is necessary to multiply the input voltage by a programmable gain, or, in other words, to create a variable-gain stage. You can easily implement a variable-gain stage using a low-cost voltage-output DAC (Figure 1). IC1 includes three independent DACs, two of which have internal buffers. This design uses the third DAC (DAC C with output OUTC) for the variable-gain stage. This no-buffer design minimizes noise and voltage offset, but you can use buffered DACs...
