3 Description
The OPA396, OPA2396, and OPA4396 (OPAx396)
feature a combination of high bandwidth (1MHz) along
with very low quiescent current (23.5μA) in a highprecision
amplifier. These features combined with
rail-to-rail input and output make these devices an
excellent choice in high-gain, low-power applications.
An ultra-low input bias current of 10fA, 100μV of offset
(maximum), and 1.2μV/°C of drift over temperature
help maintain high precision in ratiometric and
amperometric sensor front ends that have demanding
low-power requirements.
The OPAx396 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.
