Product details
Overview
MXL1007CS8 from Maxim Integrated is a low-noise, precision voltage reference IC delivering 2.5 V output with ±0.1% initial accuracy, 10 ppm/°C temperature coefficient, and 15 µVP-P noise (0.1–10 Hz). It operates from 4.5 V to 18 V supply and supports up to 10 mA load current in an 8-pin SO package, commonly used in high-resolution ADC/DAC biasing and precision instrumentation.
For engineers reviewing the MXL1007CS8 datasheet, MXL1007CS8 pinout, MXL1007CS8 application, or MXL1007CS8 equivalent, key selection criteria include initial voltage tolerance, thermal drift stability, low-frequency noise performance, supply voltage range, and SO-8 compatibility for legacy analog signal chain designs.
Technical Context
The MXL1007CS8 employs a buried-zener reference core with on-chip temperature compensation, enabling stable 2.5 V output across –40°C to +85°C. Its design targets metrology-grade systems where long-term drift and low 1/f noise are critical.
It features internal current limiting and thermal shutdown protection, and does not require external capacitors for stability-unlike bandgap references. Output impedance remains below 1 Ω at DC, supporting fast settling into capacitive loads up to 1 µF.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.5 V ±0.1% - enables direct interface with 2.5 V ADC reference inputs without scaling |
| Initial Accuracy | ±0.1% max - reduces system calibration burden in factory-trimmed instruments |
| Tempco | 10 ppm/°C max - ensures ≤0.025% output shift over full industrial temperature range |
| Noise (0.1–10 Hz) | 15 µVP-P - preserves ENOB in 18-bit+ SAR and delta-sigma converters |
| Supply Range | 4.5 V to 18 V - allows operation from unregulated rails or battery-backed supplies |
| Load Current | ±10 mA - drives multiple op-amp bias networks or reference buffers simultaneously |
Pinout & Package
MXL1007CS8 is housed in an 8-pin SOIC (SO-8) package with standard JEDEC MS-012AC outline, 1.27 mm pitch, and exposed pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VIN | Positive supply input - must be ≥4.5 V and ≤18 V; bypass capacitor recommended |
| 2 | NC | No connect - left floating; no internal connection |
| 3 | GND | Analog ground reference - tie directly to clean AGND plane |
| 4 | OUT | 2.5 V precision reference output - low-impedance source for downstream circuitry |
| 5 | NC | No connect - left floating; no internal connection |
| 6 | NC | No connect - left floating; no internal connection |
| 7 | NC | No connect - left floating; no internal connection |
| 8 | NC | No connect - left floating; no internal connection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6126AASA25+ | Bandgap-based, 2.5 V, ±0.06% initial accuracy, 3 ppm/°C tempco, higher quiescent current (120 µA) | Better tempco and accuracy but higher noise (35 µVP-P) and requires external decoupling | Preferred for new designs requiring tighter specs; not pin-compatible with MXL1007CS8 |
| REF5025IDR | Series reference, 2.5 V, ±0.05% initial accuracy, 3 ppm/°C tempco, 10 µVP-P noise, 10 mA max load | Lower noise and drift, but requires ≥3 V headroom (min 5.5 V supply), different pinout | Suitable for systems with higher supply margin; requires PCB redesign |
Compared with MXL1007CS8, MAX6126AASA25+ offers improved accuracy and thermal stability but trades off low-frequency noise and simplicity, while REF5025IDR delivers superior noise and drift performance at the cost of supply headroom and layout compatibility.

FAQ
Is MXL1007CS8 still in production?
No-MXL1007CS8 is Not Recommended for New Designs due to discontinuation of its wafer process. Aetrix Electronics maintains limited legacy stock for existing designs, with full traceability and date-code documentation. For new projects, consult Maxim/Analog Devices technical support for approved replacements such as MAX6126AASA25+ or REF5025IDR. MXL1007CS8 remains supported under Maxim's obsolescence management policy.
What is the maximum capacitive load the MXL1007CS8 can drive?
The MXL1007CS8 is stable with capacitive loads up to 1 µF without external compensation. Its low output impedance (<1 Ω) and internal compensation allow direct connection to ADC reference inputs, sample-and-hold capacitors, and op-amp bias networks. Exceeding 1 µF may cause peaking or instability; verify phase margin in target application. MXL1007CS8 datasheet Figure 5 confirms stability across 0–1 µF.
Does MXL1007CS8 require an external bypass capacitor?
Yes-a 0.1 µF ceramic capacitor between VIN and GND is recommended per the MXL1007CS8 datasheet to suppress supply noise and improve transient response. No output capacitor is required, and adding one may degrade noise performance. The MXL1007CS8 achieves stability without output capacitance due to its buried-zener architecture and internal compensation network.
Can MXL1007CS8 be used in automotive applications?
No-MXL1007CS8 is specified only for the industrial temperature range (–40°C to +85°C) and lacks AEC-Q200 qualification, automotive-grade screening, or extended-life reliability testing. Its "Not Recommended for New Designs" status further limits suitability for automotive programs. For qualified alternatives, consider the MAX6070AUT25+ or AD780BRZ, both AEC-Q200 compliant. MXL1007CS8 remains appropriate for non-automotive industrial use.
How does the noise performance of MXL1007CS8 compare to bandgap references?
MXL1007CS8 delivers 15 µVP-P (0.1–10 Hz), significantly lower than typical bandgap references (e.g., 35–60 µVP-P). This advantage stems from its buried-zener core, which exhibits inherently lower 1/f noise. In high-resolution ADC applications, this translates to ~1.5-bit higher effective resolution. MXL1007CS8's noise profile is explicitly characterized and guaranteed-not estimated-making it suitable for metrology-grade designs where bandgap alternatives fall short.
