Outstanding dynamic performance is achieved with the SHC702 companion sample/hold amplifier. Both devices use hybrid construction for applications where reliability, small size, and low power consumption are especially important. 1k Ω Excellent linearity and stability are assured through use of a new ultra-precise monolithic D/A converter and a low-drift reference circuit. Custom monolithic op amps provide very high bandwidth and low noise in all sections of the analog signal path. Logic is CMOS/TTL compatible and is designed for maximum flexibility.
