Introducing OPA333 as Bare Die Product from Texas Instruments
1.8V, 17µA, 2µV, microPOWER CMOS Zero-Drift Operational Amplifier
The OPA333 CMOS operational amplifier uses a proprietary autocalibration technique to simultaneously provide very low offset
voltage (10µV max) and near-zero drift over time and temperature.
These miniature, high-precision, low quiescent current amplifiers
offer high-impedance inputs that have a common-mode range 100mV
beyond the rails and rail-to-rail output that swings within 50mV of
the rails. Single or dual supplies as low as +1.8V (±0.9V) and up to
+5.5V (±2.75V) may be used. They are optimized for low-voltage,
single-supply operation.
The OPA333 family offers excellent CMRR without the crossover
associated with traditional complementary input stages. This design
results in superior performance for driving analog-to-digital
converters (ADCs) without degradation of differential linearity.
Designing applications with the OPA333 in bare die form allows the
designer to place the device closer to the signal source to reduce
noise pickup and increase signal integrity. Bare Die also offers >50%
X-Y-Z size reduction when compared with smallest available package.
∴Bare die form factor greatly assists size sensitive applications.
