1. Description

OPA244 (single), OPA2244 (double) and OPA4244 (four) The quiescent current of the op amp is very low (50µA/channel), but still achieve excellent bandwidth. ideal Battery-powered portable instrument, all versions are It adopts a miniature package and is suitable for space-constrained applications. Double and quad versions are completely independent Circuits that have minimal crosstalk and are not affected by interaction, even When over-driving or overloading. OPA244 series is easy to use and has no phase difference Inversion and overload problems in some other operational amplifiers. The unity gain of these amplifiers is stable, and they can maintain excellent performance when they swing to their specified limits. They can work in single voltage (+2.2V to +36V) or dual voltage Power supply (±1.1V to ±18V). Input common mode voltage The range includes grounding, which is ideal for many single-supply applications. All versions have similar performance. But there There are some differences, such as common mode rejection. All In most applications, these versions are interchangeable. All versions are available in miniature surface mount packages. OPA244 (single version) is available in a tiny 5-pin SOT-23-5 package Surface mount, SO-8 surface mount and 8-pin DIP. OPA2244 (Dual version) Available in MSOP-8 surface mount, SO-8 surface mount and 8-pin DIP. OPA4244 (four in one) Supplied with TSSOP-14 surface mount. They are fully specified The temperature range is –40°C to +85°C, and the operating temperature range is –55°C to +125°C. The SPICE macro model can be used for design analysis.
