description
●The TLV2548 and TLV2544 are a family of high performance, 12-bit low power, 3.86 µs, CMOS analog-to-digital converters (ADC) which operate from a single 2.7-V to 5.5-V power supply. These devices have 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 TI DSP, a frame sync (FS) signal is used to indicate the start of a serial data frame.
●Maximum Throughput 200-KSPS
●Built-In Reference, Conversion Clock and 8×FIFO
●Differential/Integral Nonlinearity Error: ±1 LSB
●Signal-to-Noise and Distortion Ratio: 70 dB, fi= 12-kHz
●Spurious Free Dynamic Range: 75 dB, fi= 12- kHz
●SPI (CPOL = 0, CPHA = 0)/DSP-Compatible
● Serial Interfaces With SCLK up to 20-MHz
●Single Wide Range Supply 2.7 Vdc to 5.5 Vdc
●Analog Input Range 0-V to Supply Voltage With 500 kHz BW
●Hardware Controlled and Programmable Sampling Period
●Low Operating Current (1.0-mA at 3.3-V, 1.1-mA at 5.5-V With External Ref
●Power Down: Software/Hardware Power-Down Mode (1µA Max, Ext Ref), Autopower-Down Mode (1µA, Ext Ref)
●Programmable Auto-Channel Sweep
