The OPA705NA/3K is a low-cost, CMOS operational amplifier designed for applications requiring rail-to-rail input and output. It operates over a wide supply range of 4V to 12V for single supply and ¬±2V to ¬±6V for dual supplies. The device features a low quiescent current of 160¬µA, making it suitable for battery-powered applications. It has a gain-bandwidth product of 1MHz and a slew rate of 0.6V/¬µs, providing good dynamic performance. The input offset voltage is low at 0.5mV, with a common-mode rejection ratio (CMRR) of 96dB, ensuring accurate signal amplification. The OPA705 is available in compact MicroSIZE packages, including SOT23-5, which is advantageous for space-constrained designs. It is specified for operation in a temperature range of -40¬8C to +85¬8C, making it suitable for various environments, including automotive and portable equipment applications.
