SA5211

Transimpedance amplifier (180MHz)

1998 Oct 07

853-1799 20142

DESCRIPTION

The SA5211 is a 28k

Ω transimpedance, wide-band, low noise

amplifier with differential outputs, particularly suitable for signal

recovery in fiber optic receivers. The part is ideally suited for many

other RF applications as a general purpose gain block.

FEATURES

• Extremely low noise: 1.8pA Hz

• Single 5V supply

• Large bandwidth: 180MHz

• Differential outputs

• Low input/output impedances

• High power supply rejection ratio

• 28kΩ differential transresistance

APPLICATIONS

• Fiber optic receivers, analog and digital

• Current-to-voltage converters

• Wide-band gain block

NOTES:

1. Maximum dissipation is determined by the operating ambient temperature and the thermal resistance:

θJA=125°C/W

2. The use of a pull-up resistor to VCC, for the PIN diode is recommended.
