Product details

Overview

LTC2333HLX-16#PBF from Analog Devices is a buffered 8-channel, 16-bit, 800ksps differential successive approximation register (SAR) ADC with ±10.24V input range, 30V_P-P common mode capability, and integrated 4.096V reference buffer. It operates from ±15V analog supplies and 5V digital supply, supports pin-selectable CMOS or LVDS serial interfaces, and targets high-voltage industrial data acquisition where precision, channel flexibility, and rail-to-rail overdrive tolerance are critical.

For engineers reviewing the LTC2333HLX-16#PBF datasheet, LTC2333HLX-16#PBF pinout, LTC2333HLX-16#PBF application, or LTC2333HLX-16#PBF equivalent, this page delivers verified specifications including ±1LSB INL (±10.24V range), 94.2dB SNR, 128dB CMRR, 48-pin LQFP package, and H-grade (–40°C to +125°C) operation - all confirmed for the exact LTC2333HLX-16#PBF variant.

Technical Context

The LTC2333HLX-16#PBF implements a SoftSpan™ architecture enabling per-conversion configuration of eight differential input ranges: ±10.24V, 0V to 10.24V, ±5.12V, 0V to 5.12V, ±12.5V, 0V to 12.5V, ±6.25V, and 0V to 6.25V. Its picoamp-input analog buffers maintain 128dB CMRR and –125dB active crosstalk across all channels.

It features a programmable sequencer with no-latency control, 420ns full-scale step response (0.005% settling), and dual serial interface support: SPI CMOS (1.8V–5V OVDD) or LVDS (2.375V–5.25V OVDD). Conversion timing is deterministic with t_CONV = 450–550ns and t_CYC = 1.25μs at 800ksps.

Key Specifications

Pinout & Package

48-lead (7mm × 7mm) plastic LQFP package (LX) with exposed pad; RoHS-compliant, lead-free, and qualified for extended temperature operation (–40°C to +125°C).

Pin/Terminal	Circuit Role	Design Meaning
IN0+ to IN7+	Differential analog input positive	Accepts buffered, high-impedance inputs up to VCC – 4V; supports true bipolar (IN– = 0V), fully differential (IN– = –IN+), or arbitrary common-mode drive.
IN0– to IN7–	Differential analog input negative	Defines input common mode (up to 30V_P-P) and enables flexible signal coupling without external op-amps.
VCC / VEE	Analog supply rails	Supports ±7.5V to ±16.5V operation (VCC – VEE ≤ 38V); enables direct connection to industrial ±15V power domains.

Equivalent & Alternatives

The following parts are listed as comparable options for similar 16-bit, multi-channel SAR ADC applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
AD7606C-16	8-channel, 16-bit, 1MSPS, ±10V range, internal reference, parallel/serial interface; requires external ±15V supplies but lacks SoftSpan™ range flexibility.	Targets higher-speed acquisition (1MSPS) with fixed ±10V range; less suited for mixed unipolar/bipolar signal conditioning without external multiplexers.	Select AD7606C-16 when maximum throughput >800ksps is required and input ranges are uniform across channels.
ADS8688	8-channel, 16-bit, 500ksps, ±10.24V range, integrated PGA (±0.25V to ±12.28V), SPI-only interface; operates from single 5V supply, no ±V_EE needed.	Designed for lower-power, single-supply systems; lacks differential input buffers and 128dB CMRR, limiting noise immunity in industrial settings.	Select ADS8688 when system power budget is constrained and high CMRR is not required for the target signal environment.

Compared with AD7606C-16 and ADS8688, the LTC2333HLX-16#PBF uniquely combines SoftSpan™ per-channel range programming, picoamp buffered inputs, and 128dB CMRR - making it optimal for mixed-signal industrial I/O where signal diversity, noise immunity, and temperature robustness are non-negotiable.

FAQ

What is the operating temperature range for the LTC2333HLX-16#PBF?

The LTC2333HLX-16#PBF is rated for –40°C to +125°C operation, qualifying it for under-hood automotive, industrial motor drives, and oil-and-gas downhole equipment where ambient temperatures exceed standard commercial or industrial grades. This H-grade specification is explicitly confirmed in the order information table for the LTC2333HLX-16#PBF variant.

Does the LTC2333HLX-16#PBF require external reference components?

No. The LTC2333HLX-16#PBF integrates a precision 4.096V reference buffer (REFBUF) with ±5mV initial accuracy and 20ppm/°C temperature coefficient. When REFIN is left open or tied to 0V, the internal buffer is enabled - eliminating the need for external references or buffer op-amps in most precision applications.

How does the SoftSpan™ feature work on the LTC2333HLX-16#PBF?

SoftSpan™ allows per-conversion configuration of eight differential input ranges (e.g., ±10.24V, 0–10.24V, ±5.12V) via SPI register writes. Each channel can be assigned an independent range, enabling mixed-signal acquisition - such as simultaneously measuring a ±10V pressure sensor and a 0–5V temperature sensor - without external gain switching or recalibration.

What are the power supply requirements for the LTC2333HLX-16#PBF?

The LTC2333HLX-16#PBF requires three independent supplies: analog rails VCC (7.5–38V) and VEE (–16.5–0V), and digital VDD (4.75–5.25V). OVDD supports 1.71–5.25V (CMOS) or 2.375–5.25V (LVDS). Typical power dissipation is 268mW at 800ksps in CMOS mode, with Nap and Power Down modes reducing current to 3.3mA and 0.68μA respectively.

Is the LTC2333HLX-16#PBF pin-compatible with other variants in the LTC2333 family?

Yes. All LTC2333-16 variants - including LTC2333CLX-16#PBF (0°C–70°C), LTC2333ILX-16#PBF (–40°C–85°C), and LTC2333HLX-16#PBF (–40°C–125°C) - share identical 48-lead LQFP (LX) packaging, pinout, and electrical interface. Only the temperature grade and associated parametric limits differ; no PCB layout changes are required when upgrading to the H-grade part.
