A 64-channel amplifier-comparator for a silicon strip detector fabricated using the Tektronix SHPi bipolar process is described. This device is particularly useful in high rate colliders with silicon strip vertex detection. The design requirements include near-optimum noise performance, very low power use, proton radiation resistance, and microminiature size. The detector and amplifier can be DC-coupled, since the amplifier is capable of absorbing increasing detector leakage current under irradiation. Circuit measurements show that the circuit will perform properly in its expected environment
