The HS-1135RH is a radiation hardened, High-Speed, low power current feedback amplifier built with Intersil's proprietary complementary bipolar UHF-1 (DI bonded wafer) process. They are QML approved and processed in full compliance with MIL-PRF-38535. This amplifier features user programmable output limiting, via the VH and VL pins. The HS-1135RH is the ideal choice for High-Speed, low power applications requiring output limiting (e. g. , flash A/D drivers), especially those requiring fast overdrive recovery times. The limiting function allows the designer to set the maximum and minimum output levels to protect downstream stages from damage or input saturation. The sub-nanosecond overdrive recovery time ensures a quick return to linear operation following an overdrive condition. Component and composite video systems also benefit from this op amp's performance, as indicated by the gain flatness, and differential gain and phase specifications. Specifications for Rad Hard QML devices are controlled by the Defense Supply Center in Columbus (DSCC). The SMD numbers listed here must be used when ordering. Detailed Electrical Specifications for these devices are contained in SMD 5962-96767.
