Product details
Overview
LTC1100CSW#PBF from Analog Devices (formerly Linear Technology) is a precision zero-drift instrumentation amplifier with fixed gain of 100, designed for high-accuracy DC signal conditioning in sensor interfaces. It delivers 1µV typical input offset voltage, 5nV/°C drift, 65pA max bias current, and 18kHz bandwidth - enabling thermocouple and strain gauge amplification with minimal calibration overhead.
For engineers reviewing the LTC1100CSW#PBF datasheet, LTC1100CSW#PBF pinout, LTC1100CSW#PBF application, or LTC1100CSW#PBF equivalent, key selection considerations include its self-contained gain architecture, single-supply compatibility down to 5V, CMRR optimization via Pin 2 (CMRR), bandwidth tailoring via Pin 7 (COMP), and SO-16 wide-body package thermal performance.
Technical Context
The LTC1100CSW#PBF employs chopper-stabilized zero-drift architecture with internal sampling at 2.8kHz to cancel DC offset and drift. Its dual-amplifier topology uses matched resistors for >100dB DC CMRR without trimming, while AC CMRR is enhanced via external RC network on Pin 2 (CMRR).
Gain is factory-set to 100 (non-inverting configuration); Pin 3 and Pin 14 are tied for G=10 mode only - unused in LTC1100CSW#PBF. Bandwidth is 18kHz at G=100 and can be reduced using an external capacitor from Pin 7 (COMP) to Pin 8 (VOUT), leveraging internal 247kΩ compensation resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain | Fixed 100 V/V - eliminates external resistor selection, reduces layout sensitivity and calibration burden. |
| Input Offset Voltage | ±10µV max - enables sub-100µV differential signal resolution without nulling circuitry. |
| Offset Drift | ±100nV/°C max - ensures <1µV total drift over 0°C–70°C ambient, critical for unattended industrial sensors. |
| Input Bias Current | 65pA max - supports high-impedance sources (e.g., pH electrodes, piezoresistive bridges) without loading error. |
| CMRR | 90dB min (G=100, VCM = −4.7V to 2.3V) - rejects common-mode noise in noisy industrial environments. |
| Supply Range | Single 5V or dual ±2.375V to ±8V - allows direct interface with 5V microcontrollers and legacy ±5V systems. |
| Output Swing | ±7.5V into 10kΩ load at ±8V supply - provides >300mV rail-to-rail margin for robust analog-to-digital conversion. |
| 0.1Hz–10Hz Noise | 1.9µVP-P - minimizes low-frequency noise in precision weigh scales and medical front-ends. |
Pinout & Package
Package: 16-lead plastic SO wide (SW), 0.300-inch body width, RoHS-compliant lead finish (#PBF). Thermal resistance θJA = 100°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 8, 9, 12, 16 | NC | No internal connection - must remain unconnected; floating or grounded per PCB layout rules. |
| 2 | CMRR | AC CMRR optimization node - connect 100kΩ + 10pF to ground to maximize rejection above 10Hz. |
| 3 | G = 10 | Gain-select input - shorted to Pin 2 for G=10 mode; open-circuit in LTC1100CSW#PBF (G=100 default). |
| 4 | GND REF | System ground reference - sets zero point for internal op-amp bias; must tie to clean analog ground plane. |
| 6 | –VIN | Inverting input - differential input terminal; matched impedance required for optimal CMRR. |
| 7 | COMP | Bandwidth control - external capacitor to VOUT sets dominant pole; suppresses clock feedthrough and aliasing. |
| 10 | V+ | Positive supply - accepts 5V single supply or up to +8V in dual-rail operation. |
| 11 | VIN | Noninverting input - primary differential input; high-impedance path for sensor signals. |
| 13 | VOUT | Analog output - buffered, rail-swinging output capable of driving 10kΩ loads directly into ADCs. |
| 14 | G = 10 | Gain-select input - shorted to Pin 15 for G=10 mode; open-circuit in LTC1100CSW#PBF (G=100 default). |
| 15 | V– | Negative supply - accepts 0V (single-supply) or down to –8V; referenced to GND REF (Pin 4). |
Key Features
| Feature | Design Value |
|---|---|
| Zero-drift chopper architecture | Eliminates manual offset trimming and enables <1µV system-level offset stability over time and temperature. |
| Self-contained G=100 gain | Removes external gain-setting resistor, reducing BOM count, layout area, and matching-induced errors. |
| Programmable bandwidth via COMP pin | Allows intentional bandwidth reduction (e.g., to 1Hz) to suppress switching noise or aliasing in DC-coupled systems. |
| Internal anti-aliasing circuitry | Attenuates aliasing products by ≥60dB - reduces need for external anti-alias filters in data acquisition systems. |
| Single-supply operation from 5V | Enables direct integration with 5V microcontrollers and logic without level-shifting or charge pumps. |
| Hermetic-grade matching (LTCMOS process) | Delivers >100dB DC CMRR without laser trimming - improves production yield and long-term reliability. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar instrumentation amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD8421ARZ | Fixed G=10, 10MHz bandwidth, 2.5nV/√Hz noise - higher speed but 10× larger offset drift (0.1µV/°C). | Better for fast transient sensing (e.g., pulse oximetry), less suitable for long-term DC stability (e.g., lab balances). | Select AD8421ARZ when bandwidth >100kHz is required and drift tolerance >10× higher than LTC1100CSW#PBF. |
| LTC2053IMS8#PBF | Zero-drift, G=100, 8-pin MSOP, 1.5µV offset - lower quiescent current (1.1mA vs 3.3mA) but narrower CM range (±2.5V). | Ideal for battery-powered portable instruments; limited for ±5V or industrial ±8V rails. | Choose LTC2053IMS8#PBF for space-constrained, low-power designs where supply headroom is ≤5V. |
Compared with AD8421ARZ and LTC2053IMS8#PBF, the LTC1100CSW#PBF uniquely balances ultra-low drift (±100nV/°C), fixed high gain, and wide supply flexibility (5V single or ±8V dual), making it optimal for industrial DC measurement systems requiring decades-long calibration stability.

FAQ
What is the operating temperature range for the LTC1100CSW#PBF?
The LTC1100CSW#PBF is specified for operation from –40°C to +85°C (Commercial grade). This range is validated per the Electrical Characteristics table for parameters marked with ●, including input offset drift, CMRR, and supply current. The device's LTCMOS process ensures stable performance across this full range without derating.
Can the LTC1100CSW#PBF operate from a single 3.3V supply?
No - the LTC1100CSW#PBF requires minimum ±2.375V dual supply or 5V single supply per Absolute Maximum Ratings and Electrical Characteristics tables. At 3.3V, internal amplifier headroom is insufficient for proper biasing, resulting in output saturation and degraded CMRR. Use LTC2053 or AD8237 for 3.3V-compatible alternatives.
Is the LTC1100CSW#PBF pin-compatible with the LTC1100CN8 or LTC1100CJ8?
No - the LTC1100CSW#PBF uses a 16-pin SO wide (SW) package, while LTC1100CN8/CJ8 use 8-pin PDIP/CERDIP packages with different pin functions and counts. Pin mapping, thermal characteristics, and gain configuration (G=100 vs selectable) differ fundamentally. Board redesign is required for substitution.
How does the COMP pin (Pin 7) affect noise performance in the LTC1100CSW#PBF?
The COMP pin in the LTC1100CSW#PBF connects to an internal 247kΩ resistor; adding a capacitor to VOUT forms a low-pass filter that reduces bandwidth and associated wideband noise. For example, a 100pF capacitor lowers bandwidth to ~6.5kHz and cuts integrated noise by ~30% in 0.1Hz–10Hz band - verified in TPC11 noise density plots.
Does the LTC1100CSW#PBF require external capacitors for stability?
Yes - the LTC1100CSW#PBF requires a 0.1µF bypass capacitor between V+ (Pin 10) and GND REF (Pin 4), and a 0.01µF capacitor between V– (Pin 15) and GND REF (Pin 4), as shown in Typical Application TA01. These minimize supply noise coupling and prevent oscillation due to internal chopper clock feedthrough.
