description

The TLV1548 is a CMOS 10-bit switched-capacitor successive-approximation (SAR) analog-to-digital (A/D)

converter. The device has a chip select (CS), input-output clock (I/O CLK), data input (DATA IN) and serial data

output (DATA OUT) that provides a direct 4-wire synchronous serial peripheral interface (SPI, QSPI) port

of a host microprocessor. When interfacing with a TMS320 DSP, an additional frame sync signal (FS) indicates

the start of a serial data frame. The device allows high-speed data transfers from the host. The INV CLK input

provides further timing flexibility for the serial interface.

In addition to a high-speed converter and versatile control capability, the device has an on-chip 11-channel

multiplexer that can select any one of eight analog inputs or any one of three internal self-test voltages. The

sample-and-hold function is automatic except for the extended sampling cycle, where the sampling cycle is

started by the falling edge of asynchronous CSTART. At the end of the A/D conversion, the end-of-conversion

(EOC) output goes high to indicate that the conversion is complete. The TLV1548 is designed to operate with

a wide range of supply voltages with very low power consumption. The power saving feature is further enhanced

with a software-programmed power-down mode and conversion rate. The converter incorporated in the device

features differential high-impedance reference inputs that facilitate ratiometric conversion, scaling, and

isolation of analog circuitry from logic and supply noise. A switched-capacitor design allows low-error

conversion over the full operating temperature range.

The TLV1548 has eight analog input channels. The TLV1548Q is characterized for operation from −40°C to

125°C.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
