DESCRIPTION  
SINAD = 84.5 dB, SFDR = 95 dB,  
THD = 94 dB at 15 kHz f , 200 KSPS  
in  
The TLC4541 and TLC4545 are a family of high  
performance, 16-bit, low power, miniature CMOS  
analog-to-digital converters (ADCs). These devices  
operate from a single 5-V supply. Devices are available  
with single, dual, or single pseudo-differential inputs. All  
of these devices have a chip select (CS), serial clock  
(SCLK), and serial data output (SDO) that provides a  
direct 3-wire interface to the serial port of most popular  
host microprocessors (SPI interface). When interfaced  
with a DSP, a frame sync signal (FS) is used to indicate  
the start of a serial data frame on either pin 1 (CS) or pin  
7 (FS) for the TLC4541. The TLC4545 ADC connects  
to the DSP via pin 1 only (CS).  
SPI/DSP-Compatible Serial Interfaces With  
SCLK Input up to 15 MHz  
Single 5-V Supply  
Rail-to-Rail Analog Input With 500 kHz BW  
Two Input Options Available:  
− TLC4541 − Single Channel Input  
− TLC4545 − Single Channel,  
Pseudo-differential Input

(TLC4541) Optimized DSP Interface −  
Requires FS Input Only  
Low Power With Auto-Power Down  
− Operating Current: 3.5 mA  
− Auto-Power Down Current: 5 µA  
Pin Compatible 12/14/16-Bit Family in 8-Pin  
SOIC and MSOP Packages  
The TLC4541 and TLC4545 are designed to operate  
with low power consumption. The power saving feature  
is further enhanced with an auto-power down mode.  
This product family features a high-speed serial link to  
modern host processors with an external SCLK up to  
15 MHz. Both families use a built-in oscillator as the  
conversion clock, providing a 2.94 µs maximum  
conversion time.
