Product details
Overview
LMV358IYDT from STMicroelectronics is a dual, rail-to-rail input/output operational amplifier in SO8 package, designed for low-voltage battery-powered systems. It operates from 2.7 V to 6 V, draws only 145 µA per amplifier, delivers 1 MHz gain bandwidth, and supports extended common-mode input range (VDD − 0.2 V to VCC + 0.2 V) at 25 °C - enabling precision signal conditioning in glucose meters and portable medical sensors.
For engineers reviewing the LMV358IYDT datasheet, LMV358IYDT pinout, LMV358IYDT application, or LMV358IYDT equivalent, this device is selected for ultra-low-power analog front-ends where rail-to-rail swing, sub-3 mV input offset, and AEC-Q100 qualified automotive-grade reliability are required in space-constrained SO8 layouts.
Technical Context
The LMV358IYDT integrates two independent op-amps sharing a single supply, with input stage optimized for rail-to-rail operation across full common-mode range up to VCC + 0.2 V. Its CMRR reaches 95 dB and PSRR 90 dB at 5 V supply, ensuring robust rejection of supply noise and common-mode interference in mixed-signal environments.
It features 0.45 V/µs slew rate and 48° phase margin under 600 Ω load, supporting stable unity-gain buffer and active filter configurations without external compensation. Output drive capability is ±48 mA, enabling direct interface to 2 kΩ loads while maintaining rail-to-rail output swing.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-power rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV852IST | Higher GBP (1.7 MHz), lower input bias current (1 pA vs. 63 nA), but higher supply current (220 µA) | Better for high-impedance pH or ion-selective electrodes; less suitable for ultra-low-power battery lifetime targets | Select when sensor source impedance exceeds 1 MΩ and bandwidth >1.3 MHz is required |
| LMV358IDT | Same architecture and pinout, but commercial-grade (−40 °C to 125 °C) without AEC-Q100 qualification or automotive screening | Approved for industrial and consumer equipment only; not permitted in automotive OEM designs requiring PPAP documentation | Select for cost-sensitive non-automotive applications where extended temperature validation is unnecessary |
Compared with TSV852IST, LMV358IYDT trades bandwidth and input bias for 35% lower quiescent power and automotive qualification; compared with LMV358IDT, it adds AEC-Q100 Grade 2 compliance and tighter parametric screening - making it the sole choice for safety-critical automotive cabin electronics and ISO 13485 medical devices.

FAQ
Is LMV358IYDT pin-compatible with LMV358IDT?
Yes, LMV358IYDT and LMV358IDT share identical SO8 pinout, electrical specifications, and functional behavior. The only differences are automotive qualification (AEC-Q100 Grade 2), enhanced ESD robustness, and tighter parametric screening - all implemented without altering pin assignment or footprint.
What is the maximum capacitive load the LMV358IYDT can drive without instability?
LMV358IYDT remains stable with up to 100 pF capacitive load when driving a 600 Ω series resistor, as verified in the datasheet's phase margin test condition. For larger loads (>200 pF), a 10–100 Ω isolation resistor in series with the output is required to maintain ≥44° phase margin.
Does LMV358IYDT support single-supply operation down to 2.7 V with rail-to-rail input at full temperature range?
At −40 °C to 125 °C, rail-to-rail input operation is guaranteed only when VCC ≤ 5.5 V. At 2.7 V supply, the common-mode input range is specified as VDD to VCC, meaning it reaches ground but not the positive rail - full rail-to-rail input requires ≥3.3 V supply across the full temperature range.
Can LMV358IYDT be used in a single-supply photodiode transimpedance configuration?
Yes - its rail-to-rail input allows the inverting node to be biased at VCC/2 using a low-drift divider, and rail-to-rail output accommodates full swing of the photocurrent-generated voltage. Use <1 pF feedback capacitor and 10 MΩ feedback resistor for stability; avoid connecting photodiode cathode directly to VCC due to input voltage limit constraints.
