The OPA234 series low cost op amps are ideal for  
single supply, low voltage, low power applications. 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 provides  
excellent accuracy and versatility. Single, dual, and  
quad versions have identical specifications for maxi-  
mum design flexibility. These general purpose op amps  
are ideal for portable and battery powered applications.

OPA4234  
OPA234 series op amps operate from either single or  
dual supplies. In single supply operation, the input com-  
mon-mode range extends below ground and the output  
can swing to within 50mV of ground. Excellent phase  
margin makes the OPA234 series ideal for demanding  
applications, including high load capacitance. Dual and  
quad designs feature completely independent circuitry  
for lowest crosstalk and freedom from interaction.

Single version packages are DIP-8, SO-8 surface-mount,  
and a space-saving MSOP-8 surface-mount. Dual pack-  
ages are DIP-8 and SO-8 surface-mount. Quad pack-  
ages are DIP-14 and SO-14 surface-mount. All are  
specified for –40°C to +85°C operation.

ESD damage can range from subtle performance degrada-

APPLICATIONS INFORMATION  
V+  
OPA234 series op amps are unity-gain stable and suitable  
for a wide range of general-purpose applications. Power  
supply pins should be bypassed with 10nF ceramic capaci-  
tors.  
10nF  
OPA234 single op amp only.  
Use offset adjust pins only to null  
offset voltage of op amp—see text.

OPA234 series op amps operate from single (+2.7V to  
+36V) or dual (±1.35V to ±18V) supplies with excellent  
performance. Specifications are production tested with  
+2.7V, +5V, and ±15V supplies. Most behavior remains  
unchanged throughout the full operating voltage range.  
Parameters which vary significantly with operating volt-  
age are shown in typical performance curves.  
Trim Range: ±4mV typ

FIGURE 1. OPA234 Offset Voltage Trim Circuit.  
OFFSET VOLTAGE TRIM  
Offset voltage of OPA234 series amplifiers is laser trimmed  
and usually requires no user adjustment. The OPA234  
(single op amp version) provides offset voltage trim con-  
nections on pins 1 and 5. Offset voltage can be adjusted by  
connecting a potentiometer as shown in Figure 1. This  
adjustment should be used only to null the offset of the op  
amp, not to adjust system offset or offset produced by the  
signal source. Nulling offset could degrade the offset drift  
behavior of the op amp. While it is not possible to predict  
the exact change in drift, the effect is usually small.
