The LTA806x family (LTA8061, LTA8062, and LTA8064) is a new generation of high voltage (48 V), low noise, precision operational amplifiers. These devices offer outstanding dc precision and ac performance, include low offset (±100 μV maximum), low drift (±1 μV/°C ), 1.1-MHz bandwidth, and 22 nV/√Hz Input voltage noise density at 10 kHz. Unique features such as differential input-voltage range to the negative supply rail, high output current (±40 mA), and high capacitive load drive of up to 1 nF make the LTA806x high-performance op-amps for high-voltage industrial applications.

The robust design of the LTA806x family provides ease-of-use to the circuit designer: integrated RF/EMI rejection filter, no phase reversal in overdrive conditions, and high electro-static discharge (ESD) protection. The LTA806x are optimized for operation at voltages from +4.5 V (±2.25 V) to +48 V (±24 V) over the extended temperature range of −40 °C to +125 °C.

The LTA8061 (single) is available in both SOT23-5L and SOIC-8L packages. The LTA8062 (dual) is offered in SOIC-8L and MSOP-8L packages. The quad-channel LTA8064 is offered in both SOIC-14L and TSSOP-14L packages.
