OPA137 series FET- input operational amplifiers
are designed for low cost and miniature
applications. In addition to small size (SOT-23-5
and MSOP-8 packages), amplifiers provide low input
bias current (±10pA), low quiescent current
(120µA/ channel), and high open-loop gain
(145dB).
Either single (+4.5V to +36V) or dual (±2.25V to
±18V) supplies can be used. The input common-mode
voltage range includes the positive supply an
excellent choice for many single-supply
applications. Single, dual, and quad versions have
identical specifications for maximum design
flexibility.
OPA137 op amps are easy to use and free from
phase inversion and overload problems found in
some FET- input amplifiers. High performance,
including linearity, is maintained as the
amplifiers swing to the specified limits. In
addition, the combination of high slew rate
(4.5V/µs) and wide bandwidth (1.1MHz) provide fast
settling time verifies good dynamic response. Dual
and quad designs feature completely independent
circuitry for lowest crosstalk and freedom from
interaction.
The single (OPA137) packages are the tiny 5-lead
SOT-23-5 surface mount, SO-8 surface mount, and
8-pin DIP. The dual (OPA2137) comes in the
miniature MSOP-8 surface mount, and the SO-8
surface mount. The quad (OPA4137) packages are the
SO-14 surface mount and the 14-pin DIP. All are
specified from – 40°C to +85°C and operate from –
55°C to +125°C. A SPICE macro-model is available
for design analysis.
