TLV2548, 12-bit analog-to-digital converter adc, qty 5
TLV2548IDW, 12-Bit, 200 KSPS, 8-Channel Low-Power Serial Analog-to-Digital Converter (ADC), 20 pin SOIC, Quantity 5, Texas Instruments.
The TLV2548 is a high performance, 12-bit low power, 3.86 µs, CMOS analog-to-digital converter (ADC) which operates from a single 2.7-V to 5.5-V power supply. The TLV2548 has three digital inputs and a 3-state output [chip select (CS)\, serial input-output clock (SCLK), serial data input (SDI), and serial data output (SDO)] that provide a direct 4-wire interface to the serial port of most popular host microprocessors (SPI interface). When interfaced with a TI DSP, a frame sync (FS) signal is used to indicate the start of a serial data frame.
In addition to a high-speed A/D converter and versatile control capability, this device has an on-chip analog multiplexer that can select any analog inputs or one of three internal self-test voltages. The sample-and-hold function is automatically started after the fourth SCLK edge (normal sampling) or can be controlled by a special pin, CSTART\, to extend the sampling period (extended sampling). The normal sampling period can also be programmed as short (12 SCLKs) or as long (24 SCLKs) to accommodate faster SCLK operation popular among high-performance signal processors. The TLV2548 is designed to operate with very low power consumption. The power-saving feature is further enhanced with software/hardware/autopower-down modes and programmable conversion speeds. The conversion clock (OSC) and reference are built-in. The converter can use the external SCLK as the source of the conversion clock to achieve higher (up to 2.8 µs when a 20 MHz SCLK is used) conversion speed. Two different internal reference voltages are available. An optional external reference can also be used to achieve maximum flexibility.
