The TLV1570 features a programmable internal voltage reference (3.8 V or 2.3 V) and operates from a single wide supply range of 2.7 V to 5.5 V. An internal MUX is independently accessible, which allows the user to insert a signal conditioning circuit such as an anti-aliasing filter or an amplifier, if required, between the MUX and the ADC. Therefore, one signal conditioning circuit can be used for all eight channels. Additionally, simple-to-program functions such as a unique auto-scan mode, voltage reference selection, and auto-power-down mode will benefit applications such as image sensor processing, process control, motor control, various automotive and digital servos.

Power dissipation in the TLV1570 is as low as 8 mW, making the ADC perfectly suited for portable applications. A 175-µA auto-power-down mode or 3-µA software power-down mode reduces power and heat further by signficantly reducing supply current whenever the conversion is not performed.

The TLV1570 has a typical Integral Non-Linearity (INL) of ±0.65 LSB for applications that require the most demanding accuracy specifications. It is available in two options: the 20-pin SOIC and TSSOP packages.
