信息描述The TLV2548 and TLV2544 are a family of high performance, 12-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 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, 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...

信息描述The TLV1572 is a high-speed 10-bit successive-approximation analog-to-digital converter (ADC) that operates from a single 2.7-V to 5.5-V power supply and is housed in a small 8-pin SOIC package.The TLV1572 accepts an analog input range from 0 to VCC and digitizes the input at a maximum 1.25 MSPS throughput rate. The power dissipation is only 8 mW with a 3-V supply or 25 mW with a 5-V supply. The device features an auto-powerdown mode that automatically powers down to 10 uA whenever a conversion is not performed. The TLV1572 communicates with digital microprocessors via a simple 3- or 4-wire serial port that interfaces directly to the Texas Instruments TMS320 DSPs and (Q)SPI compatible microcontrollers without using additional glue logic. Very high throughput rate, simple serial interface, SO-8 package, 3-V operation, and low power consumption make the TLV1572 an ideal choice for compact or remote high-speed systems.特性F...

信息描述The TLV1571/1578 is a 10-bit data acquisition system that combines an 8-channel input multiplexer (MUX), a high-speed 10-bit ADC, and a parallel interface. The device contains two on-chip control registers allowing control of channel selection, software conversion start, and power down via the bidirectional parallel port. The control registers can be set to a default mode by applying a dummy RD\ signal when WR\ is tied low. This allows the TLV1571/1578 to be configured by hardware. The MUX is independently accessible. This allows the user to insert a signal conditioning circuit such as an antialiasing filter or an amplifier, if required, between the MUX and the ADC. Therefore, one signal conditioning circuit can be used for all eight channels. The TLV1571 is a single channel analog input device with all the same functions as the TLV1578. The TLV1571/TLV1578 operates from a single 2.7-V to 5.5-V power supply. It accepts an ana...

信息描述The TLV2544Q, TLV2548Q, and TLV2548M are a family of high performance, 12-bit low power, 3.5 µs, CMOS analog-to-digital converters (ADC) which operate from a single 3-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 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,...
