DESCRIPTION  
The OPA684 provides a new level of performance in low-power,  
wideband, current-feedback (CFB) amplifiers. This CFBplus ampli-  
fier is 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 solutions limited by inverting input  
linearity. Beyond simple high-gain applications, the OPA684 CFBplus  
amplifier permits the gain setting element to be set with consider-  
able freedom from amplifier bandwidth interaction. This allows  
frequency response peaking elements to be added, multiple input  
inverting summing circuits to have greater bandwidth, and low-  
The output capability of the OPA684 also sets a new mark in  
performance for low-power current feedback amplifiers. Delivering  
a full ±4VPP swing on ±5V supplies, the OPA684 also has the  
output current to support this swing into a 100Ω load. This minimal  
output headroom requirement is complemented by a similar 1.2V  
input stage headroom giving exceptional capability for single +5V  
operation.  
The OPA684’s low 1.7mA 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 OPA684 supply  
current drops to less than 100µA while the I/O pins go to a high  
impedance state.
