Analog Devices Inc. LTC2320HUKG-12#TRPBF

Overview

LTC2320HUKG-12#TRPBF from Analog Devices is an octal, 12-bit + sign successive approximation register (SAR) ADC with simultaneous sampling across all eight differential input channels, 1.5 Msps per channel throughput, 77 dB SNR at 500 kHz input, and guaranteed operation up to 125°C. It serves as a high-speed data acquisition front-end in multiphase motor control systems requiring precise synchronized voltage/current sensing.

For engineers reviewing the LTC2320HUKG-12#TRPBF datasheet, LTC2320HUKG-12#TRPBF pinout, LTC2320HUKG-12#TRPBF application, or LTC2320HUKG-12#TRPBF equivalent, key selection considerations include simultaneous sampling latency, internal 4.096 V reference drift (≤20 ppm/°C), CMOS/LVDS I/O mode flexibility, 52-lead QFN package thermal performance, and bipolar zero-scale error (±1.5 LSB max).

Technical Context

The LTC2320HUKG-12#TRPBF implements eight independent SAR ADC cores sharing a common CNV timing signal to ensure true simultaneous sampling. Each core features a dedicated 4.096 V internal reference buffer (REFOUT1–4), enabling independent full-scale ranges per channel pair while maintaining <500 ps aperture delay matching.

Its digital interface supports both CMOS and LVDS modes via the CMOS/LVDS pin, with SDR/DDR configuration controlled by SDR/DDR pin. The device achieves no missing codes at 12 bits and ±0.25 LSB typical INL, with dynamic performance validated using –1 dBFS 500 kHz sine-wave inputs and internal reference.

FAQ

What is the maximum operating temperature for the LTC2320HUKG-12#TRPBF?

The LTC2320HUKG-12#TRPBF is specified for continuous operation from –40°C to +125°C, making it suitable for under-hood automotive applications, industrial motor drives, and oil & gas downhole equipment. This H-grade rating is confirmed in the Absolute Maximum Ratings table and validated across all electrical specifications in the datasheet Rev. C.

Does the LTC2320HUKG-12#TRPBF support true simultaneous sampling across all eight channels?

Yes, the LTC2320HUKG-12#TRPBF uses a single CNV edge to initiate conversion on all eight SAR cores simultaneously, with aperture delay matching guaranteed to ≤500 ps. This is explicitly stated in the General Description and verified in Table 3 (Aperture Delay Matching) of the datasheet Rev. C.

Can the internal reference of the LTC2320HUKG-12#TRPBF be disabled for use with an external reference?

Yes, the internal reference buffers (REFOUT1–4) can be disabled by grounding the REFBUFEN pin (Pin 43). When disabled, external references in the range of 1.25 V to VDD − 0.4 V may drive REFOUT1–4 pins, as documented in Table 9 and Internal Reference Characteristics section of the datasheet Rev. C.

What digital interface options does the LTC2320HUKG-12#TRPBF support?

The LTC2320HUKG-12#TRPBF supports both CMOS and LVDS serial interfaces, selected via the CMOS/LVDS pin (Pin 25). It also supports Single Data Rate (SDR) and Double Data Rate (DDR) modes via the SDR/DDR pin (Pin 23), enabling flexible FPGA interfacing with varying clock domain constraints and PCB layout requirements.

What is the power consumption of the LTC2320HUKG-12#TRPBF at full throughput?

At 5 V supply and 1.5 Msps per channel, the LTC2320HUKG-12#TRPBF dissipates 208 mW typical (PD_5V in Table 6), or ~26 mW per channel. In nap mode, power drops to 31.2 mW; in sleep mode, it falls to 525 µW - values confirmed in the Power Requirements section of datasheet Rev. C.
