LTC2314-14

14-Bit, 4.5Msps Serial

Sampling ADC in TSOT

FeaTures

DescripTion

TheLTC^®2314-14isa14-bit,4.5Msps,serialsamplingA/D

converterthatdrawsonly6.2mAfromawiderangeanalog

supply adjustable from 2.7V to 5.25V. The LTC2314-14

containsanintegratedbandgapandreferencebufferwhich

provide a low cost, high performance (20ppm/°C max)

and space saving applications solution. The LTC2314-14

achievesoutstandingACperformanceof77dBSINADand

–85dB THD while sampling a 500kHz input frequency.

The extremely high sample rate-to-power ratio makes the

LTC2314-14 ideal for compact, low power, high speed

systems. The LTC2314-14 also provides both nap and

sleep modes for further optimization of the device power

within a system.

Guaranteed 14-Bit No Missing Codes

Internal Reference: 2.048V/4.096V Span

Low Noise: 77.5dB SNR

Low Power: 6.2mA at 4.5Msps and 5V

Dual Supply Range: 3V/5V operation

Sleep Mode with < 1µA Typical Supply Current

Nap Mode with Quick Wake-up < 1 conversion

Separate 1.8V to 5V Digital I/O Supply

High Speed SPI-Compatible Serial I/O

Guaranteed Operation from –40°C to 125°C

8-Lead TSOT-23 Package

applicaTions

The LTC2314-14 has a high-speed SPI-compatible serial

interface that supports 1.8V, 2.5V, 3V and 5V logic. The

fast 4.5Msps throughput makes the LTC2314-14 ideally

suited for a wide variety of high speed applications.
