The TPA551x is the nano-power, zero-drift amplifier with a maximum 30-μV low-offset voltage and stable frequency response for the high-precision sensing application that also requires low standby power. The TPA551x devices provide rail-to-rail input and output. The devices have excellent AC performance with 9-kHz bandwidth, 3-V/ms slew rate while only drawing 650-nA quiescent current per amplifier. The TPA5511 and TPA5511U (1-ch version) are offered in the SOT23-5 and SOT353 (SC70-5) packages. The TPA5512 (2-ch version) is available in the SOP8, TSSOP8, MSOP8, DFN1.5X1.5-8, and DFN2X2-8 packages. All versions can be operated over the industrial temperature range from −40°C to +125°C.

The TPA132Q is a current-sense amplifier with a very wide input common-mode voltage range from −4 V to 80 V with a small-signal bandwidth of 1 MHz. The enhanced PWM rejection allows the TPA132Q to accommodate the solenoids and motors applications. The device features high precision accuracy specifications of Vos and the gain error, which makes it ideal for the small signal conditioning interfacing with a high accuracy ADC. Fixed gains are optional: 20 V/V, 50 V/V, 100 V/V, 200 V/V, and 500 V/V. The device offers breakthrough performance throughout the temperature range of −40°C to +125°C. The device is offered SOP8 and TSSOP8 packages. Many systems, including motors and solenoids, employ PWM signals for modulation or control purposes. However, these PWM signals generate fast common-mode voltage transitions that oscillate between high voltage and ground potential. This can pose a challenge for the current measurement circuitry, as it may result in undesirable output voltage fluctuations. To address this issue, the device incorporates an advanced PWM rejection feature. This feature minimizes the impact of common-mode voltage transitions and ensures stable and reliable output voltage.

The devices are general-purpose, unity-gain difference amplifiers for precision signal conditioning from −275-V to 275-V common voltage range. The on-chip resistors are trimmed for excellent gain accuracy and high CMRR over the operating temperature range. The TPA9151 has two reference input pins. The TPA9152 has one reference input pin at pin 1, and leaves pin 5 to NC (not connected). The devices can be used to replace isolation amplifiers in applications where the galvanic isolation is not required.

The TPA1286 is a low-cost, wide supply range instrumentation amplifier that requires only one external resistor to set any gain between 1 and 1,000. The TPA1286 is designed to work with a variety of single voltages. A wide input range and rail-to-rail output allow the signal to fully use the supply rails. Low voltage offset, low offset drift, low gain drift, high gain accuracy, and high CMRR make this part an excellent choice in applications that demand the best DC performance. The TPA1286 operates from a single 4-V to 36-V supply, and offers breakthrough performance throughout the −40°C to +125°C temperature range. It features a zerodrift core, which leads to a typical offset drift of 0.2 μV/°C throughout the operating temperature range. The TPA1286 is available in SOP8, MSOP8, and DFN3X3-8 packages.
