Precision 16-V Op Amps
feature low input-offset voltage, CMRR

May 20, 2016 By Abby Esposito

PH_PR_BAL-CC25-01D3
The low input-bias current and the energy-efficient combination of low power consumption and gain bandwidth make the TSX7 series ideal for use in power-constrained sensor-signal-conditioning applications.

STMicroelectronics has introduced the new TSX7 series of precision 16 V op amps that combine high accuracy with a wide operating-voltage range and excellent robustness. The low input-offset voltage, Common Mode Rejection Ratio (CMRR), and temperature drift eliminate any need for trimming or calibration in the assembled circuit while ensuring consistent performance over a wide automotive-grade temperature range from -40° to 125° C.

The new devices build on ST’s advanced 18 V analog manufacturing technology and the success of its TSX5, TSX6 and TSX9 series of low-power op amps.

The low input-bias current and the energy-efficient combination of low power consumption and gain bandwidth make the TSX7 series ideal for use in power-constrained sensor-signal-conditioning applications, while the wide supply-voltage range, stability in challenging operating conditions and tolerance of electrostatic discharge up to 4 kV (Human Body Model) fit well in applications such as industrial equipment, building automation, medical instrumentation, LED lighting and automotive Electronic Control Units. In addition, the rail-to-rail input and output functionality allow the TSX7 op amps to be used for low-side and high-side current measurements without limitation.

Key technical features of the new TSX7 series of precision 16 V op amps are:

  • Input offset voltage no more than 200 µV at 25° C;
  • Minimum guaranteed CMRR of 91 dB and maximum temperature drift of 2.5 µV/°C; and
  • Excellent energy-efficient combination of power consumption and gain bandwidth (GBW) with maximum Icc of 850 µA for 2.7 MHz GBW and 9 MHz GBW for gain greater than or equal to 10.

The TSX7 op amps are in volume production, with prices starting from $0.52 USD for 1,000 units.
