OPA381

Precision, Low Power, 18MHz  
Transimpedance Amplifier  
FD EATURES  
DESCRIPTION  
OVER 250kHz TRANSIMPEDANCE  
BANDWIDTH  
The OPA381 family of transimpedance amplifiers provides  
18MHz of Gain Bandwidth (GBW), with extremely high  
precision, excellent long-term stability, and very low 1/f noise.  
The OPA381 features an offset voltage of 25µV (max), offset  
drift of 0.1µV/°C (max), and bias current of 3pA. The OPA381  
far exceeds the offset, drift, and noise performance that  
conventional JFET op amps provide.

DYNAMIC RANGE: 5 Decades  
EXCELLENT LONG-TERM STABILITY  
LOW VOLTAGE NOISE: 10nV/√Hz  
BIAS CURRENT: 3pA  
OFFSET VOLTAGE: 25µV (max)  
OFFSET DRIFT: 0.1µV/°C (max)  
GAIN BANDWIDTH: 18MHz  
QUIESCENT CURRENT: 800µA  
FAST OVERLOAD RECOVERY  
SUPPLY RANGE: 2.7V to 5.5V  
SINGLE AND DUAL VERSIONS  
MicroPACKAGE: DFN-8, MSOP-8  
The signal bandwidth of a transimpedance amplifier depends  
largely on the GBW of the amplifier and the parasitic  
capacitance of the photodiode, as well as the feedback  
resistor. The 18MHz GBW of the OPA381 enables a trans-  
impedance bandwidth of > 250kHz in most configurations.  
The OPA381 is ideally suited for fast control loops for power  
level measurement on an optical fiber.  
As a result of the high precision and low-noise characteristics  
of the OPA381, a dynamic range of 5 decades can be  
achieved. This capability allows the measurement of signal  
currents on the order of 10nA, and up to 1mA in a single I/V  
conversion stage. In contrast to logarithmic amplifiers, the  
OPA381 provides very wide bandwidth throughout the full  
dynamic range. By using an external pulldown resistor to  
–5V, the output voltage range can be extended to include 0V.
