SBOS874D August 2017 – February 2021 THS4561
PRODUCTION DATA
The THS4561 is a fully differential amplifier featuring an extremely flexible supply voltage range of 2.85 V to 12.6 V, which makes this device an excellent choice for driving differential ADCs and buffering DAC outputs. This device features a low-power mode with a unique active-pullup resistor (not a conventional pullup resistor) that improves EMI reliability of the shutdown pin when left floating. This pin draws very little bias current when enabled, but increases the bias current as it nears the threshold point of shutdown. The increased current prevents the pin from unintentionally turning the device off in the presence of EMI on the disable pin. Similar to other fully differential amplifiers, the THS4561 also includes an output common-mode control pin that can be used to independently set the output common mode to match that of an ADC or other load circuit.
