Linear Tech is aiming at high-impedance sensor transimpedance amplifiers with an op-amp that requires only 3fA of bias current (typical at 25°C) while offering 500MHz gain bandwidth product. Potential applications for the chip, called LTC6268, include interfacing ADCs to reverse leakage (linear) mode photodiodes. 20kΩ transimpedance gain is available at 65MHz, and 499kΩ with 11MHz […]
