OPA205, OPA2205, OPA4205  
SBOS962F – APRIL 2020 – REVISED MARCH 2023  
OPAx205 4-µV, 0.08-µV/°C, Low-Power, Super Beta, Bipolar, e-trim™ Op Amps  
1 Features  
3 Description  
e-trimoperational amplifier performance  
– Low offset voltage: 25 µV (max),  
15 µV (max, high grade)  
– Low offset voltage drift: ±0.5 µV/°C (max),  
±0.2 µV/°C (max, high grade)  
Super beta inputs  
– Input bias current: 500 pA (max)  
– Input current noise: 110 fA/√Hz  
Low noise  
The OPA205, OPA2205, and OPA4205 (OPAx205)  
are the next generation of the industry-standard  
OPAx277 family. The OPA206 and OPA2206 are  
related devices with the same op-amp core, but with  
the added feature of input overvoltage protection  
±40 V above the supplies. These devices are  
precision, bipolar e-trimop amps with super-beta  
inputs. TI's proprietary trimming technology is used to  
achieve a typical input offset voltage of ±4 µV (±2 µV,  
high grade), and a typical input offset voltage drift of  
±0.08 µV (±0.04 µV, high grade).  
– 0.1 to 10-Hz: 0.2 µVPP  
– Voltage noise: 7.2 nV/√Hz  
AOL, CMRR, and PSRR: > 126 dB (full  
temperature range)  
Gain bandwidth product: 3.6 MHz  
Low quiescent current: 240 µA (max)  
Slew rate: 4 V/µs  
Overload power limiter  
Rail-to-rail output  
EMI and RFI filtered inputs  
Wide supply: 4.5 V to 36 V  
Temperature range: –40°C to +125°C  
Available in standard grade (OPAx205A) and  
high grade (OPA2205, preview)  
Available with ±40-V overvoltage protection in the  
OPA206 and OPA2206  
Designed on a bipolar process, the OPAx205 provide  
3.6MHz gain bandwidth for a mere 220 µA of  
quiescent current. The devices also achieve a low  
voltage noise density of only 7.2 nV/√Hz at 1 kHz.  
The super-beta inputs of the OPAx205 have a very  
low input bias current of 100 pA (typical) and a current  
noise density of 110 fA/√Hz.  
The high performance of the OPAx205 makes these  
devices an excellent choice for systems requiring  
high precision and low power consumption, such  
as flow and pressure transmitters, portable data  
acquisition (DAQ) systems, and high-density source  
measurement units (SMU).
