HA-2406 Data Sheet 30MHz, Digitally Selectable Four Channel Operational Amplifier The HA-2406 is a monolithic device consisting of four op amp input stages that can be individually connected to one output stage by decoding two TTL lines into four channel select signals. In addition to allowing each channel to be addressed, an enable control disconnects all input stages from the output stage when asserted low. Each input-output combination of the HA-2406 is designed to be a 20V/µs, 30MHz gain-bandwidth amplifier that is stable at a gain of ten. By connecting one external 15pF capacitor all amplifiers are compensated for unity gain operation. The compensation lead may also be used to limit the output swing to TTL levels through suitable clamping diodes and divider networks (see Application Note AN514). Dielectric isolation and short-circuit protected output stages contribute to the quality and durability of the HA-2406. When used as a simple amplifier, its dynamic performance is very good and when its added versatility is considered, the HA-2406 is unmatched in the analog world. It can replace a number of individual components in analog signal conditioning circuits for digital signal processing systems. Its advantages include saving board space and reducing power supply requirements. During Disable Mode VOUT goes to V-. For high output impedance during Disable, see HA2444.
