The series provides lower quiescent current than older “1013”-type products and comes in current industry- standard packages and pinouts. The combination of low offset voltage, high common-mode rejection, high power-supply rejection, and a wide supply range pro- vides excellent accuracy and versatility. Single, dual, and quad versions have identical specifications for maximum design flexibility. These general-purpose op amps are ideal for portable and battery-powered appli- cations. The OPA234 series op amps operate from either single or dual supplies. In single-supply operation, the input common-mode range extends below ground and the output can swing to within 50mV of ground. Excellent phase margin makes the OPA234 series ideal for de- manding applications, including high load capacitance. Dual and quad designs feature completely indepen- dent circuitry for lowest crosstalk and freedom from interaction. Single version packages are in an SO-8 surface-mount and a space-saving MSOP-8 surface-mount. Dual pack- ages are in an SO-8 surface-mount. Quad packages are in an SO-14 surface-mount. All are specified for –40 °C to +85°C operation. 1 2 3 4 8 7 6 5 V+ Out B –In B +In B Out A –In A +In A V– OPA2234 SO-8 A B 1 2 3 4 8 7 6 5 NC V+ Output Offset Trim Offset Trim –In +In V– OPA234 SO-8, MSOP-8 OPA2 34 OPA2 234 OPA2 34 OPA 423 4 OPA234 OPA2234 OPA4234 SBOS055B – MAY 1996 – REVISED APRIL 2008 |
