description

The TLV1544 and TLV1548 are CMOS 10-bit

switched-capacitor successive-approximation (SAR)

analog-to-digital (A/D) converters. Each device

has a chip select (CS), input-output clock (I/O

CLK), data input (DATA IN) and serial data output

(DATA OUT) that provide 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 devices allow 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 andversatile

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 TLV1544 and TLV1548 are 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.
