2.7 V至5.5 V , 10位, 200 KSPS , 4/8通道,低功耗,串行模拟数字转换器具有自动关机 2.7 V TO 5.5 V, 10-BIT, 200 KSPS, 4/8 CHANNEL, LOW POWER, SERIAL ANALOG-TO-DIGITAL CONVERTERS WITH AUTO POWER DOWN
The TLV1508 and TLV1504 are a family of high performance, 10-bit low power, 3.86 µs, CMOS analog-to-digital converters ADC which operate from a single 2.7-V to 5.5-V power supply. These devices have 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 TMS320 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, these devices have 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 TLV1508 and TLV1504 are 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.
The TLV1504I and the TLV1508I are characterized for operation from 40°C to 85°C.
