MAXIM MAX1193 Ultra-Low-Power, 45Msps, Dual 8-Bit ADC Data Sheet

19-2794; Rev 1; 9/03

Ultra-Low-Power, 45Msps, Dual 8-Bit ADC General Description Features

The MAX1193 is an ultra-low-power, dual, 8-bit, Ultra-Low Power 45Msps analog-to-digital converter (ADC). The device

57m W (Normal Operation: 45Msps)

features two fully differential wideband track-and-hold

0.3µW (Shutdown Mode)

(T/H) inputs. These inputs have a 440MHz bandwidth

Excellent Dynamic Performance

and accept fully differential or single-ended signals.

The MAX1193 delivers a typical signal-to-noise and dis- 48.5d B/48.3d B SNR at f IN = 5.5MHz/100MHz

tortion (SINAD) of 48.5d B at an input frequency of 70d Bc/68d Bc SFDR at f IN = 5.5MHz/100MHz 5.5MHz and a sampling rate of 45Msps while consum-

powers the digital output driver. In addition to ultra-low Outputs

operating power, the MAX1193 features three power- Fully Differential or Single-Ended Analog Inputs down modes to conserve power during idle periods.

Internal/External Reference Option

Excellent dynamic performance, ultra-low power, and small size make the MAX1193 ideal for applications in Multiplexed CMOS-Compatible Tri-State Outputs imaging, instrumentation, and digital communications.
