• Low Supply Current: 2.3mA max
The OPA141, OPA2141, and OPA4141 amplifier
family is a series of low-power JFET input amplifiers
• Low Offset Drift: 10mV/°C max
that feature good drift and low input bias current. The
• Low Input Bias Current: 20pA max
rail-to-rail output swing and input range that includes
• Very Low 1/f Noise: 250nV
PP
V– allow designers to take advantage of the
• Low Noise: 6.5nV/√Hz low-noise characteristics of JFET amplifiers while
also interfacing to modern, single-supply, precision
• Wide Bandwidth: 10MHz
analog-to-digital converters (ADCs) and
• Slew Rate: 20V/ms
digital-to-analog converters (DACs).
• Input Voltage Range Includes V–
The OPA141 achieves 10MHz unity-gain bandwidth
• Rail-to-Rail Output
and 20V/ms slew rate while consuming only 1.8mA
• Single-Supply Operation: 4.5V to 36V (typ) of quiescent current. It runs on a single 4.5 to
36V supply or dual ±2.25V to ±18V supplies.
• Dual-Supply Operation: ±2.25V to ±18V
All versions are fully specified from –40°C to +125°C
• No Phase Reversal
for use in the most challenging environments. The
