• UNMATCHED PRICE PERFORMANCE
The OPA330 series of CMOS operational amplifiers
offer precision performance at a very competitive
• LOW OFFSET VOLTAGE: 50μV (max)
price. These devices are members of the Zerø-Drift
• ZERO DRIFT: 0.25μV/°C (max)
family of amplifiers which use a proprietary
• LOW NOISE: 1.1μV
PP
, 0.1Hz to 10Hz
auto-calibration technique to simultaneously provide
• QUIESCENT CURRENT: 35μA (max) low offset voltage (50μV max) and near-zero drift
over time and temperature at only 35μA (max) of
• SUPPLY VOLTAGE: 1.8V to 5.5V
quiescent current. The OPA330 family features
• RAIL-TO-RAIL INPUT/OUTPUT
rail-to-rail input and output in addition to near flat 1/f
• INTERNAL EMI FILTERING
noise, making this amplifier ideal for many
applications and much easier to design into a system.
• microSIZE PACKAGES: WCSP, SC70, QFN
These devices are optimized for low-voltage
operation as low as +1.8V (±0.9V) and up to +5.5V
APPLICATIONS
(±2.75V).
• BATTERY-POWERED INSTRUMENTS
The OPA330 (single version) is available in the
• TEMPERATURE MEASUREMENTS
WCSP-5, SC70-5, SOT23-5, and SOIC-8 packages.
• TRANSDUCER APPLICATIONS
The OPA2330 (dual version) is offered in DFN-8
• ELECTRONIC SCALES
(3mm × 3mm), MSOP-8, and SOIC-8 packages. The
• MEDICAL INSTRUMENTATION
OPA4330 is offered in the standard SOIC-14 and
TSSOP-14 packages, as well as in the space-saving
• HANDHELD TEST EQUIPMENT
VQFN-14 package. All versions are specified for
• CURRENT SENSE
operation from –40°C to +125°C.
