DESCRIPTION

· The TLV1544 and TLV1548 are CMOS 10-bit switched-capacitor successive-approximation (SAR) analog-to-digital (A/D) converters.
· They feature a 4-wire synchronous serial peripheral interface (SPI, QSPI) compatible with TMS320 DSP and microprocessors.
· These devices include an on-chip 11-channel multiplexer for selecting eight analog inputs or three internal self-test voltages.
· Automatic sample-and-hold function, with extended sampling initiated by the falling edge of CSTART.
· Designed for wide supply voltage range (2.7 V to 5.5 V) with low power consumption and programmable power-down mode.

FEATURES

· 10-bit resolution ADC with conversion time ≤ 10 µs.
· Wide single-supply operation from 2.7 V to 5.5 V.
· Analog input range from 0 V to VCC.
· Built-in analog multiplexer with 8 analog input channels.
· SPI and QSPI compatible serial interfaces.
· End-of-Conversion (EOC) flag and inherent sample-and-hold function.
· Built-in self-test modes and programmable power and conversion rate.
· Asynchronous start of conversion for extended sampling.

APPLICATIONS

· Suitable for systems requiring low-power, high-speed analog-to-digital conversion.
· Ideal for applications with TMS320 DSP and microprocessor interfaces.
· Used in systems needing multiple analog input channels and self-test capabilities.
· Applicable in environments requiring wide supply voltage range and low power consumption.
