SBOS195C – MARCH 2001 – REVISED NOVEMBER 2002
200MHz, CMOS
OPERATIONAL AMPLIFIER WITH SHUTDOWN
DESCRIPTION
FEATURES
The OPA355 series high-speed, voltage-feedback CMOS
operational amplifiers are designed for video and other
applications requiring wide bandwidth. The OPA355 is unity-
gain stable and can drive large output currents. In addition,
the OPA355 has a digital shutdown (Enable) function. This
feature provides power savings during idle periods and
places the output in a high-impedance state to support output
multiplexing. Differential gain is 0.02% and differential phase
is 0.05°. Quiescent current is only 8.3mA per channel.
● UNITY-GAIN BANDWIDTH: 450MHz
● WIDE BANDWIDTH: 200MHz GBW
● HIGH SLEW RATE: 360V/µs
● LOW NOISE: 5.8nV/√Hz
● EXCELLENT VIDEO PERFORMANCE:
DIFF GAIN: 0.02%, DIFF PHASE: 0.05°
0.1dB GAIN FLATNESS: 75MHz
● INPUT RANGE INCLUDES GROUND
● RAIL-TO-RAIL OUTPUT (within 100mV)
● LOW INPUT BIAS CURRENT: 3pA
● LOW SHUTDOWN CURRENT: 3.4µA
● ENABLE/DISABLE TIME: 100ns/30ns
● THERMAL SHUTDOWN
The OPA355 is optimized for operation on single or dual
supplies as low as 2.5V (±1.25V) and up to 5.5V (±2.75V).
Common-mode input range for the OPA355 extends 100mV
below ground and up to 1.5V from V+. The output swing is
within 100mV of the rails, supporting wide dynamic range.
The OPA355 series is available in single (SOT23-6 and
SO-8), dual (MSOP-10), and triple (TSSOP-14 and SO-14)
versions. Multichannel versions feature completely indepen-
dent circuitry for lowest crosstalk and freedom from interac-
tion. All are specified over the extended –40°C to +125°C
range.
