ТPC512x 12-bit 1-MHz SAR ADC
■The TPC5120/TPC5121 products include capacitor-based SAR A/D converters with inherent sample and hold. The TPC5120 has 16-channel single-ended inputs and the TPC5121 has 8-channel single-ended inputs.
■The devices accept a wide analog supply range from 2.7 V to 5.25 V. The ultra-low power consumption makes these devices suitable for battery-powered and isolated power-supply applications.
■A wide 1.7-V to 5.25-V I/O supply range facilitates a glueless interface with the most used digital hosts. The serial interface is controlled by CS and SCLK for easy connection with microprocessors and DSP.
■The input signal is sampled with the falling edge of CS. It uses SCLK for conversion, serial data output, and reading serial data in. The devices allow auto sequencing of preselected channels or manual selection of a channel for the next conversion cycle. There are two software selectable input ranges (0 V to VREF and 0 V to 2 × VREF), individually configurable GPIOs (four in case of the TSSOP and one on the VQFN package devices), and two programmable alarm thresholds per channel. These features make the devices suitable for most data acquisition applications.
■The devices offer an attractive power-down feature. This is extremely useful for power saving when the device is operated at lower conversion speeds.
