DESCRIPTION  
The OPA857 is a wideband, fast overdrive recovery,  
fast-settling, ultralow-noise transimpedance amplifier  
targeted at photodiode monitoring applications. With  
selectable feedback resistance, the OPA857  
simplifies the design of high-performance optical  
systems. Very fast overload recovery time and  
internal input protection provide the best combination  
to protect the remainder of the signal chain from  
overdrive while minimizing recovery time. The two  
selectable transimpedance gain configurations allow  
high dynamic range and flexibility required in today's  
transimpedance amplifier applications. The OPA857  
is available in a 3-mm x 3-mm QFN package.  
130 MHz (18.2-kΩ Transimpedance,  
1.5-pF External Parasitic Capacitance)  
Ultralow Voltage Noise Density:  
14.7 nARMS (NPBW = 85.7 MHz)  
Very Fast Overload Recovery Time: < 15 ns  
Internal Input Protection Diode  
Power Supply:  
Voltage: +2.6 V to +3.6 V  
Current: 23.4 mA  
Extended Temperature Range: –40°C to +85°C  
The device is characterized for operation over the full  
industrial temperature range from –40°C to +85°C.
