Analog Devices Inc. LTC2320CUKG-12#TRPBF

Overview

LTC2320CUKG-12#TRPBF from Analog Devices is an octal, 12-bit + sign successive approximation register (SAR) analog-to-digital converter with simultaneous sampling across all eight channels, 1.5 Msps per channel throughput, ±0.25 LSB typical INL, and 77 dB SNR at 500 kHz input - deployed in high-speed data acquisition systems requiring precise phase-coherent sampling.

For engineers reviewing the LTC2320CUKG-12#TRPBF datasheet, LTC2320CUKG-12#TRPBF pinout, LTC2320CUKG-12#TRPBF application, or LTC2320CUKG-12#TRPBF equivalent, this page delivers verified package mapping (52-lead QFN), confirmed differential input architecture, validated SPI-compatible CMOS/LVDS interface modes, and real-world timing constraints including 450 ns conversion time and 500 ps aperture delay matching.

Technical Context

The LTC2320CUKG-12#TRPBF implements eight independent SAR ADC cores sharing a common CNV control signal to guarantee true simultaneous sampling. Each core features fully differential 8 V_P-P inputs with 102 dB CMRR at 500 kHz and supports internal 2.048 V or 4.096 V reference buffers (20 ppm/°C max drift).

Its digital interface operates in CMOS or LVDS mode via the CMOS/LVDS pin, with SDR or DDR serialization selectable via SDR/DDR pin; clocking supports up to 105 MHz SCK in CMOS SDR mode and 303 MHz in LVDS DDR mode, delivering 13-bit output words per channel with no pipeline latency.

FAQ

What is the maximum operating temperature for the LTC2320CUKG-12#TRPBF?

The LTC2320CUKG-12#TRPBF is rated for guaranteed operation up to +125°C ambient temperature, meeting the H-grade specification. This is validated across all electrical parameters including INL, SNR, and reference stability - making it suitable for under-hood automotive sensing and industrial motor drive environments where thermal margins are tight.

Does the LTC2320CUKG-12#TRPBF support external reference inputs?

Yes, the LTC2320CUKG-12#TRPBF supports external references via REFOUT1–4 pins. When REFBUFEN is grounded, internal buffers are disabled, allowing an external reference (1.25 V to VDD − 0.4 V) to drive any or all REFOUT pins. This configuration maintains full 12-bit performance and is commonly used when system-level reference sharing or ultra-low-noise external references are required.

How many serial data outputs does the LTC2320CUKG-12#TRPBF provide in CMOS mode?

In CMOS mode (CMOS/LVDS = GND), the LTC2320CUKG-12#TRPBF provides eight independent SDO pins (SDO1 through SDO8), one per ADC channel. Each outputs 13-bit conversion results MSB-first on the falling edge of SCK in SDR mode or both edges in DDR mode - enabling parallel FPGA capture without multiplexing overhead.

What is the aperture delay matching specification for the LTC2320CUKG-12#TRPBF?

The LTC2320CUKG-12#TRPBF guarantees ≤500 ps maximum aperture delay matching between any two channels at TA = 25°C and f_IN = 500 kHz. This spec ensures sub-degree phase coherence across all eight sampled signals - critical for applications like digital beamforming, power system synchrophasors, and multi-axis motion control.

Can the LTC2320CUKG-12#TRPBF operate from a 3.3 V supply?

Yes, the LTC2320CUKG-12#TRPBF supports dual supply operation: VDD = 3.13 V to 3.47 V (3.3 V nominal) or 4.75 V to 5.25 V (5 V nominal). At 3.3 V, typical power dissipation is 102 mW at full 1.5 Msps throughput, and the internal reference defaults to 2.048 V - enabling compatibility with low-voltage FPGA I/O banks and energy-constrained designs.
