Product details
Overview
TSV852IST from STMicroelectronics is a dual, rail-to-rail output, low-power operational amplifier with shutdown functionality, designed for precision signal conditioning in space-constrained automotive and portable systems. It delivers 1.3 MHz gain bandwidth, 0.8 mV max input offset voltage at 25 °C, 180 µA max supply current per channel at 5 V, and operates from 2.3 V to 5.5 V across –40 °C to +125 °C.
For engineers reviewing the TSV852IST datasheet, TSV852IST pinout, TSV852IST application, or TSV852IST equivalent, this device supports battery-powered sensor front-ends, automotive cabin control analog interfaces, and medical wearable signal chains where low quiescent current, high accuracy over temperature, and shutdown-enabled power gating are critical selection criteria.
Technical Context
The TSV852IST integrates two independent amplifiers with individual shutdown controls (SHDN1/SHDN2), enabling selective channel power-down without affecting adjacent circuitry. Its input stage features rail-to-rail common-mode range (VCC− − 0.2 V to VCC+ − 1 V) and low input bias current (27–60 nA typ), supporting high-impedance sensor interfacing.
Each amplifier provides rail-to-rail output swing (≤180 mV from rails into 10 kΩ), 70–75 dB CMRR at 25 °C, and stable unity-gain operation with ≥60° phase margin up to 200 pF capacitive load - verified across –40 °C to +125 °C and 2.7 V/5 V supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.3 V to 5.5 V - enables direct operation from single-cell Li-ion or 3.3 V/5 V system rails without LDO pre-regulation. |
| Gain Bandwidth Product | 1.3 MHz - supports stable closed-loop configurations up to ~100 kHz with gain ≥10, suitable for anti-aliasing and active filtering. |
| Input Offset Voltage (max) | 0.8 mV at 25 °C; 2 mV over –40 °C to +125 °C - reduces DC error in precision instrumentation without calibration. |
| Quiescent Current (per channel) | 180 µA max at 5 V - extends battery life in always-on sensor nodes; drops to 50 nA in shutdown mode. |
| Shutdown Current (per channel) | 50 nA max at 25 °C - allows microamp-level system sleep states while retaining fast wake-up (<300 ns turn-on). |
| Rail-to-Rail Output Swing | ≤100 mV from VCC− and ≤180 mV from VCC+ into 10 kΩ - maximizes dynamic range in low-voltage ADC driver applications. |
| Operating Temperature Range | –40 °C to +125 °C - qualified for under-hood automotive and industrial environments without derating. |
Pinout & Package
TSSOP-8 package (8-pin thin shrink small outline package), 3.0 mm × 4.4 mm body, 0.65 mm pitch, exposed pad optional for thermal enhancement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | In1+ | Non-inverting input of Channel 1 - accepts signals down to VCC− − 0.2 V, enabling ground-referenced sensor inputs. |
| 2 | In1− | Inverting input of Channel 1 - used for feedback configuration; high impedance (27–60 nA bias) minimizes loading on high-Z sources. |
| 3 | Out1 | Output of Channel 1 - rail-to-rail capable; sinks/source up to 35 mA (typ) at 5 V, supports direct driving of 10 kΩ loads. |
| 4 | VCC− | Negative supply rail - shared reference for both amplifiers and shutdown logic; must be connected to system ground or negative rail. |
| 5 | VCC+ | Positive supply rail - powers both channels and internal bias networks; decoupling capacitor required within 1 cm. |
| 6 | SHDN1 | Channel 1 shutdown control - logic high (≥VCC− + 0.5 V) enables amplifier; logic low (≤0.5 V) disables it and forces output to high-Z. |
| 7 | In2− | Inverting input of Channel 2 - electrically isolated from Channel 1; supports independent feedback networks. |
| 8 | In2+ | Non-inverting input of Channel 2 - identical input range and ESD tolerance (4 kV HBM) as In1+. |
Key Features
| Feature | Design Value |
|---|---|
| Low-power shutdown mode | 50 nA max per channel - enables true zero-power standby in multi-channel monitoring systems. |
| Rail-to-rail input and output | VICM = VCC− − 0.2 V to VCC+ − 1 V; VOH/VOL ≤180 mV from rails - preserves full signal swing in 2.7 V–5.5 V systems. |
| Automotive qualification | AEC-Q100 Grade 1 (–40 °C to +125 °C), 4 kV HBM ESD - certified for engine control, HVAC, and ADAS subsystems. |
| Enhanced input offset voltage | 0.8 mV max at 25 °C, 2 mV max over full temperature range - outperforms LMV358 by >2× in initial DC accuracy. |
| Stable with capacitive loads | ≥60° phase margin with up to 200 pF load - eliminates need for isolation resistors when driving ADC inputs or long traces. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-power op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV358IDR | No shutdown function; higher Vio (3 mV max); wider supply range (2.7–5.5 V); lower GBP (1 MHz). | Lacks channel-level power gating; unsuitable for duty-cycled sensor nodes requiring sub-µA sleep current. | Select when shutdown is unnecessary and cost sensitivity outweighs accuracy/power advantages. |
| TSV852IYDT | Same die, SO-8 package; identical electrical specs; no exposed pad; higher RθJA (125 °C/W vs. 100 °C/W for TSSOP-8). | Lower thermal performance limits continuous high-output-current operation in compact PCB layouts. | Select when board assembly uses standard SOIC pick-and-place and thermal dissipation is not constrained. |
Compared with LMV358IDR and TSV852IYDT, the TSV852IST uniquely combines automotive-grade temperature range, 50 nA shutdown current, and TSSOP-8 thermal efficiency - making it optimal for space- and power-critical dual-channel analog front-ends.

FAQ
What is the maximum capacitive load the TSV852IST can drive stably?
The TSV852IST maintains ≥60° phase margin with up to 200 pF capacitive load at unity gain, as verified in Figure 9 and Table 10 of the datasheet. For loads exceeding 200 pF, a series isolation resistor (≥100 Ω) is recommended between output and capacitance to preserve stability.
Does the SHDN pin require external pull-up or pull-down resistors?
No external resistors are required: the SHDN pin has internal logic threshold referencing VCC− (VIH ≥ VCC− + 0.5 V, VIL ≤ 0.5 V). However, it must never be left floating - tie directly to VCC+ to enable or VCC− to disable each channel.
Can the TSV852IST operate with a single 2.5 V supply?
Yes - the absolute minimum supply voltage is 2.3 V. At 2.5 V, all key parameters (Vio, GBP, SR, ICC) remain within datasheet limits per Table 4 and Table 6, though output swing reduces slightly (VOH/VOL increases by ~20 mV vs. 2.7 V operation).
Is the exposed pad on the TSSOP-8 package electrically connected?
No - the exposed pad on TSV852IST (TSSOP-8) is unconnected and may be left floating or soldered to a thermal pad for improved heat dissipation. It is not tied to any internal node and carries no electrical function.
