GENERAL DESCRIPTION

The ALD1712A/ALD1712B/ALD1712 is a monolithic precision operational amplifier intended primarily for a wide range of analog applications in +5V single power supply and ±5V dual power supply systems as well as +5V to +10V battery operated systems. All device characteristics are specified for +5V single supply or ±2.5V dual supply systems. It is manufactured with Advanced Linear Devices enhanced ACMOS silicon gate CMOS process and is available as a standard cell in ALDs ASIC Function-Specific library.
