DESCRIPTION  
The OPA3684 provides a new level of performance in low-power,  
wideband, current-feedback (CFB) amplifiers. This CFBPLUS am-  
plifier among the first to use an internally closed-loop input buffer  
stage that enhances performance significantly over earlier low-  
power CFB amplifiers. While retaining the benefits of very low  
power operation, this new architecture provides many of the  
benefits of a more ideal CFB amplifier. The closed-loop input stage  
buffer gives a very low and linearized impedance path at the  
inverting input to sense the feedback error current. This improved  
inverting input impedance retains exceptional bandwidth to much  
higher gains and improves harmonic distortion over earlier solu-  
tions limited by inverting input linearity. Beyond simple high-gain  
applications, the OPA3684 CFBPLUS amplifier permits the gain  
setting element to be set with considerable freedom from amplifier  
bandwidth interaction. This allows frequency response peaking  
elements to be added, multiple input inverting summing circuits to  
The output capability of the OPA3684 also sets a new mark in  
performance for low-power current-feedback amplifiers. Delivering  
a full ±4Vp-p swing on ±5V supplies, the OPA3684 also has the  
output current to support > ±3Vp-p into 50Ω. This minimal output  
headroom requirement is complemented by a similar 1.2V input  
stage headroom giving exceptional capability for single +5V opera-  
tion.  
The OPA3684’s low 1.7mA/ch supply current is precisely trimmed  
at 25°C. This trim, along with low shift over temperature and supply  
voltage, gives a very robust design over a wide range of operating  
conditions. System power may be further reduced by using the  
optional disable control pin. Leaving this disable pin open, or holding  
it HIGH, gives normal operation. If pulled LOW, the OPA3684 supply  
current drops to less than 100µA/ch while the I/O pins go to a high  
impedance state.
