OPA380  
OPA2380  
SBOS291E − NOVEMBER 2003 − REVISED NOVEMBER 2004  
Precision, High-Speed  
Transimpedance Amplifier  
FD EATURES  
DESCRIPTION  
> 1MHz TRANSIMPEDANCE BANDWIDTH  
The OPA380 family of transimpedance amplifiers provides  
high-speed (90MHz Gain Bandwidth [GBW]) operation, with  
extremely high precision, excellent long-term stability, and  
very low 1/f noise. It is ideally suited for high-speed  
photodiode applications. The OPA380 features an offset  
voltage of 25µV, offset drift of 0.1µV/°C, and bias current of  
50pA. The OPA380 far exceeds the offset, drift, and noise  
performance that conventional JFET op amps provide.

BIAS CURRENT: 50pA (max)  
OFFSET VOLTAGE: 25µV (max)  
INPUT CURRENT RANGE: 10nA to 1mA  
DRIFT: 0.1µV/°C (max)  
GAIN BANDWIDTH: 90MHz  
QUIESCENT CURRENT: 6.5mA  
SUPPLY RANGE: 2.7V to 5.5V  
SINGLE AND DUAL VERSIONS  
MicroSize PACKAGE: 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 90MHz GBW of the OPA380 enables a trans-  
impedance bandwidth of > 1MHz in most configurations. The  
OPA380 is ideally suited for fast control loops for power level  
on an optical fiber.  
AD PPLICATIONS  
PHOTODIODE MONITORING  
As a result of the high precision and low-noise characteristics  
of the OPA380, a dynamic range of 5 decades can be  
achieved. This capability allows the measurement of signal  
currents in the order of 10nA, and up to 1mA in a single I/V  
conversion stage. In contrast to logarithmic amplifiers, the  
OPA380 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.

The OPA380 (single) is available in MSOP-8 and SO-8  
packages. The OPA2380 (dual) is available in the  
miniature MSOP-8 package. They are specified from  
–40°C to +125°C.
