Description

The TPA558x is the newest zero-drift amplifier with maximum 20-μV low-offset voltage, low noise, and stable high-frequency response. It incorporates proprietary and patented design techniques to achieve excellent AC performance with 15-MHz bandwidth, 4.9-V/ μs slew rate, and low distortion while drawing 1-mA quiescent current per amplifier. The input common-mode voltage extends to V–, and the output swings rail-to-rail. The amplifier can be used as a plug-in replacement for many commercially available op-amps to improve performance. Considering the requirement of the low standby power in some special applications, there is a shutdown function which is TPA558xN series with only 7.5-μA shutdown current. The TPA5581 and TPA5581U (1-ch veision) are offered in the SOT23-5 and SC70-5 packages. The TPA5582 (2-ch version) is available in the SOP-8, TSSOP-8, MSOP-8, and DFN-8 packages. The TPA5581N (shutdown version) is only offered in the SOT23-5 package. All versions can be operated over the industrial temperature range of −40°C to +125°C.

Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime. (2) The inputs are protected by ESD protection diodes to negative power supply. If the input extends more than 300 mV beyond the negative power supply, the input current should be limited to less than 10 mA. (3) A heat sink may be required to keep the junction temperature below the absolute maximum. This depends on the power supply voltage and how many amplifiers are shorted. Thermal resistance varies with the amount of PC board metal connected to the package. The specified values are for short traces connected to the leads.

The TPA558x family of zero-drift amplifiers can operate on a single-supply voltage (2.7 V to 5.5 V), or a split-supply voltage. are presented in Typical Performance Characteristics. Figure 23.

supply. There is around 200-mV transition region at (+VS) – 1.5 V where both pairs are on. Within this transition region, PSRR, CMRR, offset voltage, offset drift, and THD can degrade comparing to that operating outside this region. Rail-to-Rail Output The TPA558x family delivers rail-to-rail output swing capability with a class-AB output stage. Different load conditions change the ability of the amplifier to swing close to the rails. Shutdown Function The shutdown function of the TPA558x is only available in the TPA558xN series. The voltage level of this is referenced to the supply voltage of the operaional amplifier. The operational amplifier is enabled with a valid high voltage and shutdown by a valid low voltage. When the single supply is used, a valid high level is defined as 0.7 × (+Vs) of the positive supply and a valid low level is defined as 0.3 × (+Vs) of the positive supply. For example, with +Vs at 5 V and −Vs at 0 V, a valid high level is defined as 3.5 V and a valid low level is defined as 1.5 V. If dual or split power supplies are used, make sure the valid high or valid low input signals are properly referred to the positive supply voltage. For example, with +Vs at 2.5V and −Vs at −2.5V, a valid high level is defined as 1 V and a valid low level is defined as −1 V. The pin of SHDN is internally pulled up to a vaild high level when this pin is left open state, so the amplifier is enabled initially if nothing is connected to the shutdown pin. The output state of the amplifier is assumed as high-impedance state if shut down. The specific requirement and performance about this function are provided in the Typical Performance Characteristics (see Figure 19 and Figure 20). The output state of the amplifier is assumed as high-impedance state if shut down. TPA5581/TPA5582 5-V, Zero-Drift, RRIO, 15-MHz, Presicion Op Amp www.3peak.com 17 / 32 AA20221203A3
