TSZ series
ultra precision amplifiers
When the highest precision matters
The TSZ amplifier series offers
low-power, zero-drift operational
amplifiers in space-saving packages.
They use chopper-stabilized
architecture that provides very low
offset voltages (8 µV max over the
full operating temperature range)
and near-zero drift.
These miniature, ultra-precision and
low quiescent current amplifiers
offer high-impedance inputs that
have a common-mode range 100
mV beyond the rails and rail-to-rail
output that swings within 50 mV of
the rails.TSZ amplifiers are optimized
for low-voltage operation with single
or dual supplies as low as
+1.8 V (±0.9 V) up to +5.5 V (±2.75 V).
The chopper architecture rejects
the high 1/f noise typically found
in CMOS input op amps, making
it suited for a wide variety of
low-frequency measurement
applications.
