LTC1404  
Complete SO-8, 12-Bit,  
600ksps ADC with Shutdown

FEATURES  
DESCRIPTION  
The LTC®1404 is a complete 600ksps, 12-bit A/D con-  
verterwhichdrawsonly75mWfroma5Vor± 5Vsupplies.  
This easy-to-use device comes complete with a 160ns  
sample-and-hold and a precision reference. Unipolar and  
bipolar conversion modes add to the flexibility of the ADC.  
The LTC1404 has two power saving modes: Nap and  
Sleep. In Nap mode, it consumes only 7.5mW of power  
and can wake up and convert immediately. In the Sleep  
mode, itconsumes60µWofpowertypically. Uponpower-  
up from Sleep mode, a reference ready (REFRDY) signal  
is available in the serial data word to indicate that the  
reference has settled and the chip is ready to convert.  
Complete 12-Bit ADC in SO-8  
Single Supply 5V or ±5V Operation  
Sample Rate: 600ksps  
Power Dissipation: 75mW (Typ)  
72dB S/(N + D) and 80dB THD at Nyquist  
No Missing Codes over Temperature  
Nap Mode with Instant Wake-Up: 7.5mW  
Sleep Mode: 60µW  
High Impedance Analog Input  
Input Range (1mV/LSB): 0V to 4.096V or ± 2.048V  
Internal Reference Can Be Overdriven Externally  
3-Wire Interface to DSPs and Processors (SPI and  
MICROWIRETM Compatible)  
The LTC1404 converts 0V to 4.096V unipolar inputs from  
a single 5V supply and ±2.048V bipolar inputs from ±5V  
supplies. Maximum DC specs include ±1LSB INL, ±1LSB  
DNL and 45ppm/°C full-scale drift over temperature.  
Guaranteed AC performance includes 69dB S/(N + D)  
and 76dB THD at an input frequency of 100kHz over  
temperature.
