The TS507 is a new high precision, single-channel op-amp featuring
an ultra-low input offset voltage of only 25 µV typical and 100
µV maximum. This high precision is obtained by trimming after packaging,
using a patented adjustment technique. One main advantage of adjustment
after packaging is the avoidance of offset voltage drift due to
encapsulation. In addition to a low offset voltage, the TS507 demonstrates
excellent DC parameters, an openloop gain of 131 dB (typ.) on a
5 V supply, and a PSRR of 105 dB (typ.).
Operating at low supply voltages from 2.7 to 5.5 V,
the TS507 has a rail-to-rail configuration on both its input and
output. It can also deliver high output current -up to 130 mA in
a short circuit configuration- and can drive high capacitive loads.
It consumes 850 µA and has a gain bandwidth product of 1.9 MHz.
The TS507, like the recent TSV91x and TSV99x, has an exceptional
ESD tolerance of above 5 kV in HBM.
The TS507 benefits applications requiring high precision to amplify
low-level signals delivered by low-source impedance sensors. The
low supply voltage makes it perfect for battery-powered applications,
portable medical instrumentation and devices, test equipment and
factory automation applications. The TS507 is also qualified for
automotive use.
