DESCRIPTION
The OPA334 and OPA335 series of CMOS operational
amplifiers use auto-zeroing techniques to simultaneously
provide very low offset voltage (5µV max), and near-zero drift
over time and temperature. These miniature, high-precision,
low quiescent current amplifiers offer high input impedance
and rail-to-rail output swing. Single or dual supplies as low as
+2.7V (±1.35V) and up to +5.5V (±2.75V) may be used.
These op amps are optimized for low-voltage, single-supply
operation.
The OPA334 family includes a shutdown mode. Under logic
control, the amplifiers can be switched from normal operation
to a standby current of 2µA. When the Enable pin is con-
nected high, the amplifier is active. Connecting Enable low
disables the amplifier, and places the output in a high-
impedance state.
The OPA334 (single version with shutdown) comes in
MicroSIZE SOT23-6. The OPA335 (single version without
shutdown) is available in SOT23-5, and SO-8. The OPA2334
(dual version with shutdown) comes in MicroSIZE MSOP-10.
The OPA2335 (dual version without shutdown) is offered in
the MSOP-8 and SO-8 packages. All versions are specified
for operation from –40°C to +125°C.
