INA129P

The INA129P is a low-power general purpose Instrumentation Amplifier offering excellent accuracy. The versatile 3 op-amp design and small size make this amplifier ideal for a wide range of applications. Current-feedback input circuitry provides wide bandwidth even at high gain (200kHz at G=100). A single external resistor sets any gain from 1 to 10000. The INA12x is laser-trimmed for very low offset voltage (50µV) and high common-mode rejection (120dB at G≥100). The INA12x operates with power supplies as low as ±2.25V and quiescent current is only 700µA, ideal for battery-operated systems. Internal input protection can withstand up to ±40V without damage.

• Input protected to ±40V
• 0.5μV/°C Maximum low drift
• 5nA Maximum low input bias current
• Green product and no Sb/Br
