OPA381

OPA2381

SBOS313B − AUGUST 2004 − REVISED NOVEMBER 2004

Precision, Low Power, 18MHz

Transimpedance Amplifier

F_DEATURES

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.
