LTC2323-12

Dual, 12-Bit + Sign, 5Msps

Differential Input ADC with Wide

Input Common Mode Range

FEATURES

DESCRIPTION

The LTC^®2323-12 is a low noise, high speed dual

12-bit + sign successive approximation register (SAR)

ADC with differential inputs and wide input common mode

5Msps Throughput Rate

±±.5ꢀSꢁ INꢀ ꢂTꢃpꢄ

Guaranteed 12-ꢁit, No Missing Codes

Differential Inputs with Wide Input Common

range. Operating from a single 3.3V or 5V supply, the

LTC2323-12 has an 8V_P-Pdifferential input range, making

it ideal for applications which require a wide dynamic

range with high common mode rejection. The LTC2323-

12 achieves ±±.5LSꢀ INL typical, no missing codes at 12

bits and 73dꢀ SNR.

Reference

1.8V to 2.5V I/O Voltages

CMOS or LVDS SPI-Compatible Serial I/O

Power Dissipation 38mW/Ch (Typ)

Small 28-Lead (4mm × 5mm) QFN Package

The LTC2323-12 has an onboard low drift (2±ppm/°C max)

2.±48V or 4.±96V temperature-compensated reference.

The LTC2323-12 also has a high speed SPI-compatible

serial interface that supports CMOS or LVDS. The fast

5Msps per channel throughput with one-cycle latency

makes the LTC2323-12 ideally suited for a wide variety of

high speed applications. The LTC2323-12 dissipates only

38mW per channel and offers nap and sleep modes to

reduce the power consumption to 5μW for further power

savings during inactive periods.
