1.8V, 15MHz Low-Offset,
Low-Power, Rail-to-Rail I/O Op Amps
Typical Operating Characteristics
(VDD = 3.3V, VSS = 0V, VIN+ = VIN- = VDD/2, RL = 10kI to VDD/2, VCAL = VSHDN = VDD, TA = -40NC to +125NC. Typical values are at
TA = +25NC, unless otherwise noted. All devices are 100% production tested at TA = +25NC. Temperature limits are guaranteed by design.)
