118 Présentation
Background on MPN disambiguation: a manufacturer part number (MPN) is a unique alphanumeric identifier assigned by a semiconductor vendor to a specific die, package, and operating-grade variant. Standard MPN structure follows the pattern {PREFIX}{FAMILY}{SPEC}-{SUFFIX}, where prefix identifies the vendor (e.g. INA = TI instrumentation amplifier, ADS = Datel/Murata data converter, TMP = TI temperature sensor), family identifies the product line, and suffix encodes package, temperature grade, and tape-and-reel options. Bare numeric strings like '118' typically appear as either a SUFFIX (e.g. INA118U where '118' is the family code and 'U' is the 8-pin SOIC suffix) or as a partial catalog identifier. Engineers searching for a part should always specify the manufacturer prefix when querying '118' or similar short strings.
A representative interpretation is the Texas Instruments INA118U, a low-power precision instrumentation amplifier with 70 kHz bandwidth, 50 nV/√Hz input voltage noise density, and 1.4 mA typical quiescent current, packaged in an 8-pin SOIC. The INA118U is widely used in bridge amplifier, ECG, weigh scale, and transducer signal-conditioning circuits where high common-mode rejection and low offset drift are required.
Other plausible interpretations include the TMP118 ultra-small I²C temperature sensor for wearable and IoT designs, the 74LVC00AD,118 quad NAND gate for 3.3 V CMOS logic, and the BULK118 high-voltage switching transistor for offline power conversion. Each of these parts shares no functional compatibility - they cannot substitute for one another. Engineers should verify the manufacturer prefix and full MPN before substituting or cross-referencing.
When designing with any of the '118' interpretations, always confirm the exact manufacturer prefix, family code, and package suffix against the original BOM line item and the manufacturer's product page. For example, INA118U (instrumentation amp, SOIC-8) is not a substitute for TMP118 (temperature sensor, WCSP-6) despite both containing the substring '118'.
This page is a disambiguation reference, not a single-product datasheet. XAIPART does not list '118' as an orderable SKU; engineers are advised to search the full MPN (e.g. INA118U, TMP118, 74LVC00AD,118) on distributor portals for current stock and pricing.

Applications typiques
118 convient pour 6 applications: Bridge Amplifier Signal Conditioning (representative INA118U use), Medical ECG Front-End (representative INA118U use), Industrial Process Control Transducer Interface (representative INA118U use), Weigh Scale and Force Measurement (representative INA118U use), Portable and Wearable Temperature Sensing (representative TMP118 use), High-Voltage Switching Power Conversion (representative BULK118 use).
Bridge Amplifier Signal Conditioning (representative INA118U use)
The INA118U's 110 dB minimum CMRR at 1 kHz and 50 nV/√Hz input voltage noise make it ideal for bridge-type sensors such as load cells, pressure transducers, and strain gauges. The on-chip matched laser-trimmed resistor network sets gains from 1 to 1000 via a single external resistor, eliminating the discrete resistor matching that degrades discrete op-amp instrumentation amp designs. A typical 4-wire load-cell application uses gain=100 to amplify a 1 mV/V full-scale signal into a 0-5 V ADC range, and the INA118U's 5 µV max input offset voltage preserves calibration accuracy across the operating temperature range.
Recommandé
Medical ECG Front-End (representative INA118U use)
The INA118U's high CMRR (110 dB min at 1 kHz) and low input bias current (2.5 nA max) qualify it for the front-end of battery-powered ECG and bio-impedance monitors where 50/60 Hz mains common-mode interference must be rejected. The 70 kHz bandwidth supports both diagnostic (0.05-150 Hz) and monitoring (0.5-40 Hz) bandwidths without saturating on motion artefacts. Its 1.4 mA quiescent current is acceptable for wearable designs; for lower-power designs, the INA118U can be duty-cycled via the shutdown pin (when available on the SOIC variant).
Recommandé
Industrial Process Control Transducer Interface (representative INA118U use)
The INA118U's ±18 V dual or 2.7-36 V single supply operation tolerates industrial 24 V loop-powered and 4-20 mA interfaces directly without external level shifters. Its 1.4 mA quiescent current keeps heat dissipation low in DIN-rail mounted signal-conditioning modules, while 5 µV max input offset preserves linearity for thermocouple cold-junction and RTD bridge circuits. Designers should add RC low-pass filtering at the input for ESD and EMI immunity per the TI INA118 application note SBOA204.
Recommandé
Weigh Scale and Force Measurement (representative INA118U use)
The INA118U's low input voltage noise (50 nV/√Hz) and high gain accuracy (0.5% max from laser-trimmed resistors) suit precision weigh-scale designs where 0.01% resolution is required. The on-chip gain-setting resistor minimizes temperature-coefficient mismatch that plagues discrete designs, while the 70 kHz bandwidth accommodates the fast settling required by dynamic weighing platforms. The SOIC-8 footprint simplifies PCB layout versus multi-op-amp alternatives, and the INA118U's 5 µV max input offset voltage drifts only 0.5 µV/°C, maintaining calibration over -40 to +85°C.
Recommandé
Portable and Wearable Temperature Sensing (representative TMP118 use)
The TMP118's 0.336 mm² WCSP package and 240 µm thickness suit space-constrained wearable skin-temperature patches, smart-watch thermal monitoring, and IoT environmental sensors where board area is at a premium. The ±0.1°C accuracy from -10 to +85°C supports clinical-grade skin temperature reporting, while the I²C/SMBus interface allows multi-sensor bus-sharing with other low-power peripherals. The 240 µA active current and 1.5 µA standby current enable year-long coin-cell operation when duty-cycled at 1 Hz.
Recommandé
High-Voltage Switching Power Conversion (representative BULK118 use)
The STMicroelectronics BULK118 high-voltage fast-switching NPN power transistor targets offline flyback, forward, and PFC switching converter topologies where 800 V-1500 V breakdown and fast switching minimize switching losses. Its planar die structure provides consistent switching performance across the operating temperature range, and its TO-220 or TO-247 package options handle 5-15 W dissipation with proper heatsinking. Designers should observe the safe operating area (SOA) curve in the datasheet for inductive-load switching and add RCD snubbers to limit Vce overshoot.

Notes de conception
Searching for the bare numeric string '118' on distributor portals returns zero or ambiguous results because it is not a complete manufacturer part number. A valid MPN includes a manufacturer prefix (e.g. INA, TMP, ADS) that disambiguates the product family. Before ordering or substituting, always verify the full MPN against the BOM line item and the manufacturer's official product page (ti.com, st.com, nxp.com, etc.). Engineers using parametric search must include the prefix to get a single part result.
For the representative INA118U interpretation, place the gain-setting resistor as close to pins 1 and 8 as possible to minimize leakage and stray capacitance, which degrade CMRR at high gains. Use a guard ring around the input pins connected to pin 5 (input sense) to reduce PCB leakage by orders of magnitude. Maintain symmetrical trace layout between pins 2 and 3 to preserve CMRR. Reference the TI INA118 datasheet layout section for the recommended PCB pattern.
When using the INA118U on a single supply (e.g. +5 V only), bias the reference pin (pin 5) at mid-supply (e.g. +2.5 V via a resistor divider) to allow true bipolar input swing on the bridge. Add 0.1 µF ceramic bypass capacitors within 5 mm of pins 7 (V+) and 4 (V-) to suppress supply noise. Estimated quiescent current is 1.4 mA from the TI datasheet, so a 5 V/10 mA LDO is sufficient for analog supply rails.
Informations de conformité
Compliance cannot be determined for the ambiguous MPN '118'. Per-part compliance must be checked against the full MPN (e.g. INA118U is RoHS compliant per TI product page; TMP118 is RoHS and REACH compliant).
