Product details
Overview
MAT14ARZ from Analog Devices is a monolithic quad NPN transistor array optimized for precision analog signal conditioning, offering matched current gain (ΔhFE ≤ 4%), low voltage noise density (3 nV/√Hz max at 100 Hz), and low offset voltage (400 µV max) - ideal for log amplifiers and low-noise op amp front ends.
For engineers reviewing the MAT14ARZ datasheet, MAT14ARZ pinout, MAT14ARZ application, or MAT14ARZ equivalent, key selection criteria include guaranteed transistor matching across all four devices, bulk resistance (rBE ≤ 0.6 Ω), thermal stability over −40°C to +85°C, and SOIC_N-14 packaging with substrate isolation pins.
Technical Context
The MAT14ARZ integrates four identical NPN transistors on a single die with shared substrate connection (Pins 4 & 11), enabling precise parametric matching in current mirrors and log circuits. Its design includes protection diodes across each base-emitter junction to prevent beta degradation under reverse bias.
It operates with guaranteed hFE ≥ 300 at IC = 10 µA–1 mA and VCB ≤ 30 V, supports fT ≥ 300 MHz at IC = 1 mA, and delivers logarithmic conformance validated by ΔVOS/ΔIC ≤ 50 µV over 10 µA–1 mA - critical for accurate analog computation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad NPN transistor array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM394H | TO-99 metal can package; higher noise (5 nV/√Hz); no substrate pins; wider VOS spread (±1 mV) | Used in legacy military/aerospace analog computers; lacks SOIC_N footprint and substrate isolation | Choose LM394H only when hermetic packaging or radiation tolerance is required |
| SSM2212 | Dual NPN only; no substrate terminals; lower hFE match (8%); 100 µV typical VOS but not guaranteed max | Suitable for stereo audio biasing; insufficient for 4-quadrant log or quad-mirror topologies | Select SSM2212 only for dual-channel applications where quad integration is unnecessary |
Compared with LM394H and SSM2212, the MAT14ARZ uniquely combines quad integration, substrate isolation, guaranteed 4% hFE match, and SOIC_N-14 manufacturability - making it the only option for production-grade, thermally stable, 4-transistor analog computation circuits.

FAQ
What is the maximum operating temperature range for the MAT14ARZ?
The MAT14ARZ is specified for continuous operation from −40°C to +85°C ambient temperature. All key parameters - including current gain match (ΔhFE ≤ 4%), offset voltage (VOS ≤ 520 µV), and noise density (≤3 nV/√Hz) - are guaranteed across this full industrial temperature range per the official Analog Devices datasheet Rev. A.
Does the MAT14ARZ require external compensation for log amplifier use?
No, the MAT14ARZ does not require external compensation for basic log amplifier configurations. Its inherent logarithmic conformance - validated by ΔVOS/ΔIC ≤ 50 µV and rBE ≤ 0.6 Ω - ensures stable operation with standard op amp feedback. However, high-speed or wide-dynamic-range log designs may need external capacitor compensation per Figure 18 in the MAT14ARZ datasheet.
Are Pins 4 and 11 of the MAT14ARZ electrically identical?
Yes, Pins 4 and 11 of the MAT14ARZ are internally connected as a single substrate node. The dual substrate pins provide layout flexibility: one can be grounded while the other routes to the most negative system potential, minimizing capacitive coupling between transistors in sensitive analog circuits.
Can the MAT14ARZ replace discrete transistor arrays in existing current mirror designs?
Yes, the MAT14ARZ can directly replace discrete matched transistor arrays in current mirror designs - provided the PCB layout accommodates the SOIC_N-14 footprint and substrate pins are correctly tied to the most negative potential. Its guaranteed 4% hFE match and integrated protection diodes improve long-term stability versus hand-matched discretes.
What is the meaning of "R-14" in the MAT14ARZ ordering guide?
"R-14" is the Analog Devices package option code for the 14-lead standard small outline integrated circuit (SOIC_N) package, compliant with JEDEC MS-012-AB. It specifies the narrow-body 8.75 mm × 4.00 mm outline, 1.27 mm lead pitch, and gull-wing lead form used for the MAT14ARZ - distinct from wider SOIC or TSSOP variants.
