] OPA244 (single channel), OPA2244 (dual channel), and OPA4244 (four channels) operational amplifiers are designed for very low static current (50 μA/channel), but can achieve excellent bandwidth. The ideal battery power supply and portable gesture instruments, all versions are characterized by limited micro -packaging applications dual and four -way versions are completely independent circuits to reduce the interaction of string disturbances and freedom, even at speeding or overloads.

The OPA244 series is easy to use, and there is no phase reversal and overload problem in other operations. In order to maintain good performance and stability restrictions in the amplifier. They can operate from single power (+2.2V to+36V) or dual power supply (± 1.1V to ± 18V). The input of a co -mode voltage range includes the ideal grounding of many single power applications. All versions have similar performance. But there are some differences, such as co -model suppression. In most applications, all versions are exchanged.

All versions provide micro-surface installation packaging .oPa244 (single version) with micro 5-draw SOT-23-5 surface installation, SO-8 surface installation and 8-needle DIP. OPA2244 (dual version) can be used for MSOP-8 surface installation, SO-8 surface installation and 8-needle DIP. OPA4244 (Quad) is installed on TSSOP-14 surface. They are completely specified between -40 ° C and+85 ° C, and work at -55 ° C to+125 ° C. SPICE macro model can be used for design and analysis.

Application information OPA244 isThe unit gain is stable and suitable for extensive universal applications.0.01 μF ceramic capacitors should be used to bypass the power. Working voltage

OPA244 can work at a single power supply (+2.2V to+36V) or dual power supply (± 1.1 to ± 18V), which has excellent performance.Different from most of the operation amplifier specified at a power supply voltage, OPA244 is designed for practical applications; within the power range of+2.6V to+36V (± 1.3 to ± 18V), there is a set of specifications.

This allows the designer to have the same performance guarantee under any power supply voltage in this range.In addition, many key parameters are within the specified temperature range, namely -40 ° C to+85 ° C.Without the entire working voltage range, most of the performance remains unchanged.The typical performance curve shows parameters with significant changes in operating voltage or temperature.
