DescriptionThe TLV2544CD is designed as one member of the TLV2544 family which would be high performance, 12-bit low power, 3.6 ms, CMOS analog-to-digital converters (ADC) which operate from a single 2.7V to 5.5V power supply. TLV2544CD has 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.
TLV2544CD has twelve features. (1) Maximum throughput 200 KSPS. (2) Built-in reference, conversion clock and 8× FIFO. (3) Differential / integral nonlinearity error ±1 LSB. (4) Signal-to-noise and distortion ratio 69dB, fi = 12 kHz. (5) Spurious free dynamic range 75 dB, fi = 12 kHz. (6) SPI/DSP compatible serial interfaces with SCLK up to 20 MHz. (7) Single wide range supply 2.7Vdc to 5.5Vdc. (8) Analog input range 0V to supply voltage with 500 kHz BW. (9) Hardware controlled and programmable sampling period. (10) Low operating current (1mA at 2.7V, 1.2 mA at 5.5V external ref, 1.6 mA at 2.7V, 2.1 mA at 5.5V, internal ref). (11) Power down software / hardware, power-down mode (1 mA max, ext ref), auto power-down mode (1 mA, ext ref). (12) Programmable auto-channel sweep. That are all the main features.
Some absolute maximum ratings of TLV2544CD have been concluded into several points as follow. (1) Its supply voltagr range, GND to Vcc would be from -0.3V to 6.5V. (2) Its analog input voltage range would be from -0.3V to Vcc+0.3V. (3) Its reference input voltage would be Vcc+0.3V. (4) Its digital input voltage range would be from -0.3V to Vcc+0.3V. (5) Its operating virtual junction temperature range would be from -40°C to 150°C. (6) Its operating free-air temperature range would be from 0°C to 70°C. (7) Its storage temperature range would be from -65°C to 150°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device. And so on.
