Linear Tech's LTC6360 op amp drives SAR ADCs to 0V on 5V supply

摘要

The LTC6360 op amp drives 16-and 18-bit SAR ADCs. It can drive to 0V and maintain high linearity on a 5V supply through its integrated ultra-low-noise charge pump. Maximum input offset voltage is less than 250 μV, and noise is 2.3 n/√Hz. The device settles to 16 bits in 150 nsec and achieves a closed-loop -3-dB bandwidth of 250 MHz.
