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.
