AD9114/AD9115/AD9116/AD9117
FEATURES
GENERAL DESCRIPTION
Power dissipation @ 3.3 V, 20 mA output
191 mW @ 10 MSPS
The AD9114/AD9115/AD9116/AD9117 are pin-compatible
dual, 8-/10-/12-/14-bit, low power digital-to-analog converters
(DACs) that provide a sample rate of 125 MSPS. These TxDAC®
converters are optimized for the transmit signal path of commu-
nication systems. All the devices share the same interface, package,
and pinout, providing an upward or downward component
selection path based on performance, resolution, and cost.
232 mW @ 125 MSPS
Sleep mode: <3 mW @ 3.3 V
Supply voltage: 1.8 V to 3.3 V
SFDR to Nyquist
86 dBc @ 1 MHz output
85 dBc @ 10 MHz output
The AD9114/AD9115/AD9116/AD9117 offer exceptional ac and
dc performance and support update rates up to 125 MSPS.
AD9117 NSD @ 1 MHz output, 125 MSPS, 20 mA: −162 dBc/Hz
Differential current outputs: 2 mA to 20 mA
2 on-chip auxiliary DACs
The flexible power supply operating range of 1.8 V to 3.3 V and
low power dissipation of the AD9114/AD9115/AD9116/AD9117
make them well suited for portable and low power applications.
CMOS inputs with single-port operation
Output common mode: adjustable 0 V to 1.2 V
Small footprint 40-lead LFCSP RoHS-compliant package
PRODUCT HIGHLIGHTS
1. Low Power. DACs operate on a single 1.8 V to 3.3 V supply;
total power consumption reduces to 225 mW at 100 MSPS.
Sleep and power-down modes are provided for low power
idle periods.
APPLICATIONS
Wireless infrastructures
Picocell, femtocell base stations
Medical instrumentation
2. CMOS Clock Input. High speed, single-ended CMOS clock
input supports a 125 MSPS conversion rate.
Ultrasound transducer excitation
Portable instrumentation
3. Easy Interfacing to Other Components. Adjustable output
common mode from 0 V to 1.2 V allows for easy interfacing
to other components that accept common-mode levels
greater than 0 V.
Signal generators, arbitrary waveform generators
