Wide-Bandwidth, DC Restoration Circuit  
FEATURES  
DESCRIPTION  
•
PROPAGATION DELAY: 1.9ns  
The OPA615 is a complete subsystem for very fast  
and precise DC restoration, offset clamping, and  
low-frequency hum suppression of wideband ampli-  
fiers or buffers. Although it is designed to stabilize the  
performance of video signals, the circuit can also be  
used as a sample-and-hold amplifier, high-speed  
integrator, or peak detector for nanosecond pulses.  
•
BANDWIDTH:  
OTA: 710MHz  
Comparator: 730MHz  
•
•
LOW INPUT BIAS CURRENT: ±1µA  
SAMPLE-AND-HOLD SWITCHING  
TRANSIENTS: ±5mV

high-impedance cascode current source output and  
fast and precise sampling comparator that together  
set a new standard for high-speed applications. Both  
the OTA and the sampling comparator can be used  
as stand-alone circuits or combined to form a more  
complex signal processing stage. The self-biased,  
bipolar OTA can be viewed as an ideal volt-  
age-controlled current source and is optimized for low  
input bias current. The sampling comparator has two  
identical high-impedance inputs and a current source  
output optimized for low output bias current and offset  
voltage; it can be controlled by a TTL-compatible  
switching stage within a few nanoseconds. The  
transconductance of the OTA and sampling  
comparator can be adjusted by an external resistor,  
allowing bandwidth, quiescent current, and gain  
trade-offs to be optimized.
