3 Description
The INA129-EP device is a low power, generalpurpose instrumentation amplifier offering excellent accuracy. The versatile 3-op amp design and small size make the device ideal for a wide range of applications. Current-feedback input circuitry provides wide bandwidth even at high gain (200 k Hz at G = 100).
A single external resistor sets any gain from 1 to 10,000. The INA129-EP provides an industrystandard gain equation; the INA129-EP gain equation is patible with the AD620.
The INA129-EP device is laser trimmed for very low offset voltage, drift, and high mon-mode rejection (113 d B at G ≥ 100). It operates with power supplies as low as ±2.25 V, and quiescent current is only 750 μA- ideal for battery operated systems. Internal input protection can withstand up to ±40 V without damage.
The INA129-EP is available in a 8-Pin SOIC surfacemount package specified for the
- 55°C to 125°C temperature range.
