Product details

Overview

LTC2415-1CGN#PBF from Analog Devices (formerly Linear Technology) is a micropower 24-bit delta-sigma analog-to-digital converter with differential input and reference, integrated oscillator, 2 ppm INL, 0.23 ppm RMS noise, and 2.7V–5.5V supply. It delivers simultaneous 50 Hz/60 Hz ±2% notch rejection (>87 dB normal-mode) and single-cycle settling for multiplexed sensor digitization in precision industrial instrumentation.

For engineers reviewing the LTC2415-1CGN#PBF datasheet, LTC2415-1CGN#PBF pinout, LTC2415-1CGN#PBF application, or LTC2415-1CGN#PBF equivalent, key selection criteria include its 13.75 Hz output rate, 49–61.2 Hz simultaneous line-frequency rejection, GND-to-VCC common-mode input/reference range, 200 µA supply current, and SSOP-16 package compatibility with SO-8 footprints.

Technical Context

The LTC2415-1CGN#PBF implements a delta-sigma modulator with decimating FIR filter and auto-calibration architecture, enabling true no-latency conversion-each output corresponds directly to one analog sample without pipeline delay or redundant data. Its internal oscillator eliminates external timing components while supporting configurable notch frequencies via the FO pin.

It operates in three deterministic states-Conversion, Sleep, and Data Output-with CS-controlled wake-up and SDO-driven serial readout. The 3-wire SPI/MICROWIRE-compatible interface supports both internal and external SCK modes, and the device maintains DC common-mode rejection >140 dB across GND–VCC input and reference common-mode ranges.

Key Specifications

Parameter	Value and Actual Design Meaning
Resolution	24-bit with no missing codes-guarantees monotonicity and full dynamic range utilization for high-precision measurement.
INL	2 ppm of VREF-enables sub-1 ppm effective resolution in calibrated systems, critical for 6½-digit DVMs and strain gage transducers.
RMS Noise	0.23 ppm of VREF-translates to ~1.1 µV_RMS at 5 V reference, supporting 0.1 µV-level signal resolution in low-drift applications.
Output Rate	13.75 Hz-optimized for simultaneous 50 Hz/60 Hz line rejection over 49–61.2 Hz range without external clock tuning.
Supply Current	200 µA in conversion mode, 20 µA in sleep-enables battery-powered portable instrumentation with multi-year runtime.
Common-Mode Range	GND to VCC for both inputs and reference-supports ratiometric remote sensing, floating bridge measurements, and wide-range sensor biasing.
Input Rejection	87 dB normal-mode at 49–61.2 Hz (FO = GND)-provides robust immunity to AC mains interference in unshielded industrial environments.

Pinout & Package

Package: 16-lead plastic SSOP (GN), 0.150" body width, SO-8 footprint compatible, operating temperature range 0°C to 70°C (C-grade).

Pin/Terminal	Circuit Role	Design Meaning
GND (Pins 1, 7, 8, 9, 10, 15, 16)	Ground reference	Seven dedicated ground pins internally tied-require low-impedance connection to PCB ground plane for optimal noise immunity and decoupling.
VCC (Pin 2)	Positive supply	2.7V–5.5V operation; requires 10 µF tantalum + 0.1 µF ceramic bypass close to pin for stable low-noise performance.
REF+ / REF– (Pins 3, 4)	Differential reference inputs	Accept 0.1V–VCC differential voltage; common-mode independently set from GND to VCC-enables flexible ratiometric and isolated sensing.
IN+ / IN– (Pins 5, 6)	Differential analog inputs	Support –0.5×VREF to +0.5×VREF differential range; common-mode range extends beyond rails (GND–0.3V to VCC+0.3V) for robust front-end interfacing.
FO (Pin 14)	Frequency control	Configures notch behavior: GND enables simultaneous 50/60 Hz rejection (LTC2415-1); VCC or external clock selects discrete 50 Hz or 60 Hz mode (LTC2415).
CS (Pin 11)	Chip select	Active-low enable: LOW wakes ADC and initiates data output; HIGH forces sleep mode (20 µA) and places SDO in Hi-Z.
SDO (Pin 12)	Serial data output	3-state output delivering 32-bit conversion result; reflects conversion status when CS is LOW but no SCK active.
SCK (Pin 13)	Serial clock	Bidirectional: outputs internal clock during data transfer (internal mode) or accepts external clock (external mode); auto-configured at power-up or CS edge.

Key Features

Feature	Design Value
No latency ∆Σ architecture	Single-cycle settling ensures each output corresponds exactly to one analog sample-eliminates filter delay and simplifies time-critical multiplexed sensor systems.
Simultaneous 50/60 Hz rejection	87 dB normal-mode rejection over 49–61.2 Hz range with FO = GND-enables global deployment without hardware or firmware reconfiguration.
Integrated oscillator	No external crystal, capacitor, or resistor required-reduces BOM count, board space, and calibration drift associated with external timing components.
GND-to-VCC common-mode range	Both input and reference common-mode voltages independently adjustable across full supply rail-supports direct connection to unbuffered bridges and remote sensors.
Low-power sleep mode	20 µA quiescent current with CS = HIGH-extends battery life in portable DMMs, handheld analyzers, and IoT edge nodes.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-precision delta-sigma ADC applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ADS124S08IPW	24-bit, 4 kSPS, integrated PGA and burn-out current sources; requires external reference; 1.8V–3.6V supply only.	Targeted at RTD/thermocouple systems needing programmable gain and sensor excitation-not optimized for simultaneous dual-line-frequency rejection.	Select when system requires on-chip PGA, sensor diagnostics, or lower supply voltage; avoid if 50/60 Hz simultaneous rejection or 2.7V–5.5V operation is mandatory.
LTC2440CGN#PBF	24-bit, 120 Hz max output rate, 110 dB 50/60 Hz rejection (single-frequency), higher supply current (350 µA), same SSOP-16 package.	Designed for faster sampling with deeper notch at single frequency-lacks LTC2415-1's 49–61.2 Hz simultaneous rejection capability.	Select when higher throughput (up to 120 Hz) and deeper single-frequency rejection are prioritized over ultra-low power and global line-frequency coverage.

Compared with ADS124S08IPW and LTC2440CGN#PBF, the LTC2415-1CGN#PBF uniquely balances ultra-low power (200 µA), simultaneous 50/60 Hz immunity, and rail-to-rail common-mode flexibility-making it optimal for battery-powered, globally deployed precision measurement where timing simplicity and EMI resilience are critical.

FAQ

What is the maximum output data rate of the LTC2415-1CGN#PBF?

The LTC2415-1CGN#PBF has a fixed output data rate of 13.75 Hz when using its internal oscillator with FO = GND. This rate is optimized to provide simultaneous 50 Hz and 60 Hz ±2% line-frequency rejection across the 49–61.2 Hz band. External clocking allows adjustment, but the native configuration delivers this precise rate for global EMI immunity without user tuning.

How does the FO pin configure the LTC2415-1CGN#PBF for dual-line-frequency rejection?

The FO pin on the LTC2415-1CGN#PBF must be tied to GND to activate simultaneous 50 Hz/60 Hz rejection. In this state, the internal digital filter achieves ≥87 dB normal-mode rejection across 49–61.2 Hz. Connecting FO to VCC configures the part for 50 Hz-only rejection (LTC2415 behavior), while an external clock on FO enables user-defined notch frequencies per f_EOSC/2560.

Does the LTC2415-1CGN#PBF require external passive components for oscillator operation?

No, the LTC2415-1CGN#PBF contains a fully integrated, factory-trimmed oscillator. No external crystals, capacitors, or resistors are needed to achieve specified 13.75 Hz output rate and 87 dB line-frequency rejection. This eliminates timing-component variability and reduces PCB area and BOM cost versus discrete oscillator solutions.

What is the input common-mode voltage range supported by the LTC2415-1CGN#PBF?

The LTC2415-1CGN#PBF supports independent input common-mode voltage (VINCM) and reference common-mode voltage (VREFCM) ranges from GND to VCC. This allows direct interfacing with unbuffered Wheatstone bridges, thermocouples, and other sensors whose common-mode voltage may float anywhere within the supply rails-without level-shifting circuitry.

Can the LTC2415-1CGN#PBF operate from a 3.3V supply while maintaining full 24-bit performance?

Yes, the LTC2415-1CGN#PBF is fully specified from 2.7V to 5.5V. At 3.3V supply, it maintains 24-bit resolution with no missing codes, 2 ppm INL, and 0.23 ppm RMS noise-verified across the 0°C to 70°C temperature range. Supply current remains 200 µA in conversion mode, ensuring consistent low-power operation regardless of nominal rail voltage.
