Features
• Broad supply spectrum:
- 3 V to 36 V (B, BA versions)
- 3 V to 30 V (LMx24, LM2902V)
• Minimum low input offset voltage at 25 °C:
- 2 mV (BA versions LM2902A, LM124A)
- 3 mV (B versions LMx24xA)
• Maximum low input bias current at 25 °C:
- 35 nA (B, BA versions)
• HBM 2-kV ESD protection (B, BA, K versions)
• Internal filter for RF and EMI (B, BA versions)
• Typical low quiescent current of 175 A/ch
• VCC- and below are common-mode input voltage ranges.
• The range of the differential input voltage is equal to the rated supply voltage.
• 100-V/mV typical open-loop differential voltage amplification
• Unless otherwise stated, all parameters are evaluated on items that comply with MIL-PRF-38535. Production processing does not always include checking each parameter for all other items.
These components are made up of four separate high-gain, frequency-compensated operational amplifiers that have been engineered particularly to run off of a single supply over a broad variety of voltages. Operation from split supplies is also feasible if VCC is at least 1.5 V more positive than the input common-mode voltage, the difference between the two supplies is 3 V to 36 V (for B and BA versions), 3 V to 26 V (for LM2902 devices), or 3 V to 30 V (for all other devices). The supply voltage's size has no bearing on the low supply-current drain. Applications include DC amplification modules, transducer amplifiers, and any other operational amplifier circuits that were previously difficult to implement in single-supply-voltage systems.
A variety of signal conditioning applications benefit from the usage of the operational amplifiers LMx24 and LM2902. With numerous supply circuits, inputs can be powered before VCC for flexibility.
An operational amplifier's typical use is as an inverting amplifier. This amplifier converts the input voltage from positive to negative to the same magnitude. It also transforms negative voltages into positive voltages in the same way.
