Mixed Signal/Analog
Dual ADC Drivers from Linear Technology
Linear Technology has announced what it says is the LTC6420-20 and LTC6421-20, the industry’s first high-speed dual differential ADC drivers with guaranteed gain matching, and exceptional noise and distortion performance. With guaranteed matched gain of ±0.25dB and matched phase of ±0.1° (typ), the LTC6420-20 reduces errors in multichannel systems such as IQ demodulation or diversity receivers. Channel separation is 80dB at 100MHz.
The The LTC6420-20 and LTC6421-20 are the dual versions of our award-winning LTC6400/LTC6401, says Brian Black, Product Marketing Manager. These new products extend the benefits of outstanding noise and distortion performance, low voltage operation, and excellent stability to applications which require close matching between ADC channels.
The LTC6420-20 is ideal for processing signals from DC to 300MHz. LTC6421-20 is a lower power (40mA) version of the LTC6420-20 and is optimized for lower input frequencies of DC to 140MHz.
