TSX920, TSX921, TSX922, TSX92310 MHz rail-to-rail CMOS 16 V operational amplifiers Datasheet - production data Features • Rail-to-rail input and output • Wide supply voltage: 4 V - 16 V • Gain bandwidth product: 10 MHztyp at 16 V • Low power consumption: 2.8 mA typ per amplifier at 16 V • Unity gain stable • Low input bias current: 10 pA typ • High tolerance to ESD: 4 kV HBM • Extended temperature range: -40 °C to 125 °C • Automotive qualification Related products • See the TSX5 series for low-power features • See the TSX6 series for micro-power features • See the TSX929 series for higher speeds • See the TSV9 series for lower voltages Applications • Communications • Process control • Test equipment Description The TSX92x single and dual operational amplifiers (op amps) offer excellent AC characteristics such as 10 MHz gain bandwidth, 17 V/ms slew rate, and 0.0003 % THD+N. These features make the TSX92x family particularly well-adapted for communications, I/V amplifiers for ADCs, and active filtering applications. Their rail-to-rail input and output capability, while operating on a wide supply voltage range of 4 V to 16 V, allows these devices to be used in a wide range of applications. Automotive qualification is available as these devices can be used in this market segment. Shutdown mode is available on the single (TSX920) and dual (TSX923) versions enabling an important current consumption reduction while this function is active. The TSX92x family is available in SMD packages featuring a high level of integration. The DFN8 package, used in the TSX922, with a typical size of 2x2 mm and a maximum height of 0.8 mm offers even greater package size reduction.

Notes: Typical value is based on the Vio drift observed after 1000 h at 125 °C extrapolated to 25 °C using the Arrhenius law and assuming an activation energy of 0.7 eV. The operational amplifier is aged in follower mode configuration (see Section 5.5: "Long term input offset voltage drift"). (2) When used in comparator mode, with high differential input voltage, during a long period of time with VCC close to 16 V and Vicm>VCC/2, Vio can experience a permanent drift of a few mV drift. This phenomenon is notably worse at low temperatures.

Application information Application information Operating voltages The TSX92x operational amplifiers can operate from 4 V to 16 V. The parameters are fully specified at 4.5 V, 10 V, and 16 V power supplies. However, parameters are very stable in the full VCC range. Additionally, main specifications are guaranteed in the extended temperature range from -40 to 125 °C. Rail-to-rail input The TSX92x series is designed with two complementary PMOS and NMOS input differential pairs. The device has a rail-to-rail input and the input common mode range is extended from (VCC-) - 0.1 V to (VCC+) + 0.1...

Input offset voltage drift over temperature The maximum input voltage drift over the temperature variation is defined as the offset variation related to offset value measured at 25 °C. The operational amplifier is one of the main circuits of the signal conditioning chain, and the amplifier input offset is a major contributor to the chain accuracy. The signal chain accuracy at 25 °C can be compensated during production at application level. The maximum input voltage drift over temperature enables the system designer to anticipate the effect of temperature variations. The maximum input...
