Dual Differential Amplifier/ADC Driver Delivers 10GHz Gain Bandwidth with 1.1nV/√Hz Noise
2017-03-22 | ReturnThe LTC6419 dual differential amplifier, with its DC coupling, low noise and high bandwidth capabilities, is well suited for many applications such as direct conversion receivers, driving high sample rate ADCs, high speed data acquisition systems, test instrumentation, high resolution radar systems, advanced image sensors and LIDAR systems.
The LTC6419 has a supply voltage range from 2.7V to 5.25V. Each amplifier also has a shutdown pin, so each amplifier can be enabled independently, drawing a nominal supply current of 52mA. When disabled, the supply current reduces to 100µA per amplifier.
The LTC6419 is offered in a small 4mm x 3mm x 0.75mm, 20-lead LQFN plastic package. Two grades are offered: an I grade rated from ̶ 40°C to 85°C and an H grade from ̶40°C to 125°C. The LTC6419 I grade is priced starting at $8.50 and the H grade starting at $9.90 each in 1,000-pieces quantities. Both are available immediately in production quantities. For more information, visit www.linear.com/product/LTC6419.
Summary of Features: LTC6419
• Configurable Gain and Bandwidth: Unity Gain at 1.4GHz
o Gain = 100 at 100MHz
o Gain = 400 at 30MHz
• 1.1nV/Hz Input Voltage Noise Density with 40kHz Noise Corner Frequency
• Wide DC Common Mode Voltage Range:
o Input 0V to 3.5V
o Output: 0.5V to 3.5V
• Channel Separation 95dB at 100MHz
• Industrial and High Temperature Grades Offered:
o I Grade: –40°C to 85°C
o H Grade: –40°C to 125°C
