Product details

Overview

LTC2358HLX-16#PBF from Analog Devices is a 16-bit, 8-channel simultaneous-sampling SAR ADC with buffered differential inputs, ±10.24V input range, 200ksps per channel throughput, and 94.2dB SNR. It features per-channel SoftSpan™ programmable input ranges (±10.24V/0–10.24V/±5.12V/0–5.12V), 128dB CMRR, and rail-to-rail input overdrive tolerance - deployed in high-voltage industrial process monitoring systems requiring wide dynamic range and channel-to-channel isolation.

For engineers reviewing the LTC2358HLX-16#PBF datasheet, LTC2358HLX-16#PBF pinout, LTC2358HLX-16#PBF application, or LTC2358HLX-16#PBF equivalent, this page delivers verified specifications including true bipolar drive capability, picoamp-level input leakage (500pA max at 85°C), LVDS/CMOS dual-interface support, and H-grade −40°C to +125°C operation - critical for power line monitoring, PLC analog input modules, and test equipment design.

Technical Context

The LTC2358HLX-16#PBF implements an 8-channel simultaneous sampling architecture using independent analog input buffers with 500pA max input leakage at 85°C and 12nA at 125°C. Its SoftSpan™ configuration enables per-conversion selection of four differential input ranges via SPI register writes, supporting both true bipolar (IN− = 0V) and fully differential (IN− = −IN+) signal drives without external level-shifting circuitry.

It integrates a 4.096V reference buffer (REFBUF), internal conversion clock, and dual-mode serial interface: pin-selectable CMOS (1.8V–5V OVDD) or LVDS. Conversion timing includes 500ns/channel typical conversion time, 450ns minimum acquisition time per channel, and no cycle latency - enabling deterministic real-time sampling in closed-loop control applications.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
AD7606C-16	16-bit, 8-channel, ±10V range, 1MSPS total throughput (125ksps/channel), integrated analog front-end with anti-aliasing filter; uses single 5V supply only.	Optimized for lower-power, lower-cost systems where ±10V range suffices and simultaneous sampling jitter <1ns is not required.	Select AD7606C-16 when system-level power budget is constrained and external high-voltage supplies are unavailable.
ADS8688	16-bit, 8-channel, ±10.24V range, 1MSPS total throughput (125ksps/channel), integrated PGA (×0.25 to ×4), single 5V supply; no LVDS option.	Targets applications needing programmable gain for mixed-signal sensor types (e.g., strain gauges + thermistors) without external amplification.	Select ADS8688 when variable gain per channel is required and LVDS noise immunity is unnecessary.

Compared with AD7606C-16 and ADS8688, the LTC2358HLX-16#PBF delivers higher per-channel throughput (200ksps vs. 125ksps), superior SNR (94.2dB vs. 92.5dB), and wider analog supply flexibility (±15V compatible), making it optimal for high-fidelity, high-voltage industrial digitization where timing determinism and noise rejection are paramount.

FAQ

What is the maximum sampling rate per channel for the LTC2358HLX-16#PBF?

The LTC2358HLX-16#PBF achieves 200ksps per channel when all eight channels are enabled simultaneously. This rate scales with active channel count: 225ksps with seven channels, up to 800ksps with one channel enabled. The device maintains guaranteed 16-bit no-missing-codes performance across all rates, and its internal conversion clock eliminates cycle latency for deterministic timing in real-time control loops.

Does the LTC2358HLX-16#PBF support true bipolar input configurations?

Yes, the LTC2358HLX-16#PBF supports true bipolar drive where IN− is tied to 0V (ground), enabling direct digitization of ±10.24V, ±5.12V, or other symmetric ranges without external level-shifting circuitry. This is distinct from fully differential mode (IN− = −IN+) and arbitrary common-mode configurations - all selectable per channel via SoftSpan™ registers. The device guarantees ±1LSB INL in true bipolar ±10.24V mode across its full −40°C to +125°C operating range.

How does the LTC2358HLX-16#PBF handle input overvoltage conditions?

The LTC2358HLX-16#PBF provides rail-to-rail input overdrive tolerance: analog inputs (IN+/IN−) may exceed V_CC or fall below V_EE by up to ±(V_CC−V_EE) without corrupting conversions on other channels. Internal clamping diodes safely shunt up to 10mA above V_CC or below V_EE, and the 12nA max input leakage at 125°C ensures minimal DC error during overvoltage events - critical for protecting downstream signal chains in industrial field wiring.

What reference voltage options are available for the LTC2358HLX-16#PBF?

The LTC2358HLX-16#PBF offers two reference modes: internal 4.096V buffered reference (REFBUF) or external reference applied to REFIN (1.25–2.2V range). When REFIN is driven externally, the internal reference buffer must be disabled by grounding REFIN. The REFBUF output remains stable at 4.096V ±0.025% full-scale error over temperature, with ±2.5ppm/°C drift - eliminating need for external reference ICs in most high-accuracy applications.

Is the LTC2358HLX-16#PBF pin-compatible with other members of the LTC2358 family?

Yes, the LTC2358HLX-16#PBF shares identical 48-lead LQFP (LX) package, pinout, and electrical interface with LTC2358CLX-16#PBF (0°C to 70°C) and LTC2358ILX-16#PBF (−40°C to 85°C). All variants use the same SoftSpan™ configuration registers, timing parameters, and functional specifications - allowing drop-in replacement across temperature grades without PCB or firmware changes. Only the guaranteed operating temperature range differs between grades.
