Differential amplifier drives DC-coupled 100-MHz signals with low noise
October 12, 2010 // Paul Buckley
Linear Technology has introduced a fully differential amplifier capable of driving DC to 100 MHz signals with 1.1 nV/√Hz noise and -88 dBc HD2/HD3 distortion. Built on an advanced SiGe BiCMOS process, the LTC6409 features 10 GHz gain-bandwidth product, 100 dB SFDR up to 40 MHz, and 1% settling time of 1.9 ns.
The device is ideal for driving the latest high speed ADCs such as the 1.8 V 14-bit 150 Msps LTC2262-14. The LTC6409 features wide input common mode range of 0 V to 3.5 V and output common mode range of 0.5 V to 3.5 V when using a single 5 V supply, making it easy to interface ground-referenced signals to differential pipeline ADCs.
Gain and feedback resistors are external, allowing the designer to configure the exact gain needed for each application. The amplifier is unity gain stable and high output current of up to 95 mA allows it to drive lower value feedback and gain resistors, such as 150 Ohm, resulting in low output noise.
The LTC6409 is fully specified to operate with either a 3 V or 5 V single supply. Despite its wide bandwidth and low noise performance, supply current power consumption is 56 mA max and a shutdown mode reduces this to 500 uA when turned off. Turn-on time is typically 160 ns.
The LTC6409 will find use in pulsed signal applications such as radar signal processing, imaging, high speed test and measurement and communications applications.
Availability and Pricing
The LTC6409 is available in a 2 mm x 3 mm QFN package, fully specified over the C- (0 to 70 degrees C), I- (-40 to 85 degrees C) and H- (-40 to 125 degrees C) temperature grade ranges. Prices start at 4.50 US Dollars each in 1,000 piece quantities.
