DESCRIPTION
OPA234 series low-cost amps ideal single-supply, low-voltage, low-power applications. series provides lower quiescent current than older "1013"-type products comes current industrystandard packages pinouts. combination offset voltage, high common-mode rejection, high power-supply rejection, wide supply range provides excellent accuracy versatility. Single, dual, quad versions have identical specifications maximum design flexibility. These general-purpose amps ideal portable battery-powered applications. OPA234 series amps operate from either single dual supplies. single-supply operation, input common-mode range extends below ground output swing within 50mV ground. Excellent phase margin makes OPA234 series ideal demanding applications, including high load capacitance. Dual quad designs feature completely independent circuitry lowest crosstalk freedom from interaction. Single version packages SO-8 surface-mount space-saving MSOP-8 surface-mount. Dual packages SO-8 surface-mount. Quad packages SO-14 surface-mount. specified -40°C +85°C operation.

APPLICATIONS INFORMATION
OPA234 series amps unity-gain stable suitable wide range general-purpose applications. Power-supply pins should bypassed with 10nF ceramic capacitors.
10nF
OPA234 single only. offset adjust pins only null offset voltage amp-see text. OPA234 10nF 100k Trim Range: ±4mV (V-) single supply operation.
OPERATING VOLTAGE
OPA234 series amps operate from single (+2.7V +36V) dual (±1.35V ±18V) supplies with excellent performance. Specifications production tested with +2.7V, +5V, ±15V supplies. Most behavior remains unchanged throughout full operating voltage range. Parameters which vary significantly with operating voltage shown Typical Characterisitc curves.
FIGURE OPA234 Offset Voltage Trim Circuit.
OFFSET VOLTAGE TRIM
Offset voltage OPA234 series amplifiers laser trimmed usually requires user adjustment. OPA234 (single version) provides offset voltage trim connections pins Offset voltage adjusted connecting potentiometer, shown Figure This adjustment should used only null offset amp, adjust system offset offset produced signal source. Nulling offset could degrade offset drift behavior amp. While possible predict exact change drift, effect usually small.
