descriptionThe 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 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 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.
