3 Description
The OPA391 and OPA2391 (OPAx391) feature a
unique combination of high bandwidth (1 MHz)
along with very-low quiescent current (24 μA) in
high-precision amplifiers. These features combined
with rail-to-rail input and output make these devices
an exceptional choice in high-gain, low-power
applications. Ultra-low input bias current of 10 fA,
only 45 μV of offset (maximum), and 1.2 μV/°C of
drift over temperature help maintain high precision in
ratiometric and amperometric sensor front ends that
have demanding low-power requirements.
The OPAx391 use Texas Instrument's proprietary
e‑trim™ operational amplifier technology, enabling a
unique combination of ultra-low offset and low input
offset drift without the need for any input switching or
auto-zero techniques. The CMOS-based technology
platform also features a modern, robust output stage
design that is tolerant of high output capacitance,
alleviating stability problems that are common in
typical low-power amplifiers.
