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-trim^™operational 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-trim^™op 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 µV_PP

– Voltage noise: 7.2 nV/√Hz

A_OL, 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

3.6‑MHz 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).
