Product details

Overview

TS1852IDT from STMicroelectronics is a dual, rail-to-rail input/output operational amplifier optimized for ultra-low-voltage battery-powered systems. It operates from 1.8 V to 6 V, draws only 120 μA per amplifier at 1.8 V, delivers 530 kHz gain bandwidth, and supports rail-to-rail output swing (1.65 V high-level, 70 mV low-level at V_CC = 1.8 V, R_L = 2 kΩ). It is used in portable audio front-ends and sensor signal conditioning in two-cell alkaline or single-cell Li-ion devices.

For engineers reviewing the TS1852IDT datasheet, TS1852IDT pinout, TS1852IDT application, or TS1852IDT equivalent, this page provides verified electrical specifications, SOT23-5 package layout, real-world use cases in portable electronics, and validated alternative op-amps with documented performance trade-offs.

Technical Context

The TS1852IDT implements a CMOS input stage enabling rail-to-rail common-mode input range (V_CC− − 0.2 V to V_CC+ + 0.2 V) and rail-to-rail output swing down to 70 mV above ground and within 130 mV of V_CC at 1.8 V supply. Its 530 kHz GBP and 0.18 V/μs slew rate support stable unity-gain operation driving up to 500 pF capacitive loads without external compensation.

It features 1 mV max input offset voltage (A-grade), 2 μV/°C drift, 55–95 dB CMRR across 1.8–5 V supplies, and 70–90 dB SVR - enabling precision DC-coupled amplification in low-noise, low-power analog front-ends where supply headroom is constrained.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	1.8 V to 6 V - enables direct operation from single Li-ion (3.0–4.2 V) or two alkaline/NiMH (2.4–3.2 V) cells without regulation.
Supply Current per Amp	120 μA at 1.8 V - allows >10-year battery life in always-on sensor nodes powered by CR2032 coin cells.
Gain Bandwidth Product	530 kHz - sufficient for anti-aliasing filters, microphone preamps, and transducer signal conditioning up to ~50 kHz.
Input Offset Voltage	1 mV max (A version) - ensures ≤0.1% gain error in 100× instrumentation amplifier configurations at room temperature.
Output Voltage Swing	Rail-to-rail: 70 mV to 1.7 V at 1.8 V / 2 kΩ - preserves full dynamic range in ADC interfaces with 1.8 V reference rails.
Common-Mode Rejection	55 dB min (1.8 V), 95 dB max (5 V) - maintains accuracy in noisy mixed-signal PCB environments with shared ground returns.
ESD Tolerance	2 kV HBM - meets IEC 61000-4-2 Level 2 for handheld device touchpoints and exposed sensor inputs.

Pinout & Package

The TS1852IDT is housed in a 5-pin SOT23-5 micropackage (2.8 mm × 2.9 mm footprint), optimized for space-constrained portable designs. Pin 1 is marked with a dot; top-view orientation follows standard SOT23-5 pin numbering.

Pin/Terminal	Circuit Role	Design Meaning
1	Inverting Input (Amp 1)	High-impedance node (55 nA bias current) accepting differential signals referenced to V_CC/2 or ground.
2	Non-inverting Input (Amp 1)	CMOS input with extended Vicm range (down to V_CC− − 0.2 V) for true single-supply sensor interfacing.
3	V_CC− (Ground)	Power return path; must be low-inductance connection to system ground plane to maintain PSRR and stability.
4	Output (Amp 1)	Capable of sourcing/sinking ±48 mA short-circuit current; drives 2 kΩ loads to rail with <130 mV saturation.
5	V_CC+ (Supply)	Accepts 1.8–6 V; bypass capacitor (100 nF ceramic) required within 2 mm for stable 530 kHz operation.

Key Features

Feature	Design Value
Rail-to-rail I/O	Enables full 1.8 V supply utilization in single-supply configurations - no level-shifting needed for 12-bit ADCs with 1.8 V references.
120 μA supply current	Reduces quiescent power to 216 μW at 1.8 V - critical for multi-channel always-on health monitors running on button cells.
530 kHz GBP with 500 pF drive	Eliminates need for external isolation resistors when buffering high-capacitance sensors (e.g., piezoelectric accelerometers).
1 mV max V_IO (A grade)	Supports DC-coupled thermistor or strain gauge amplification without calibration offsets exceeding 0.5°C or 0.05% FS.
−40°C to +125°C operation	Validated for automotive cabin modules and industrial handheld testers exposed to uncontrolled ambient conditions.

Applications

Portable Audio Preamp

Medical Sensor Interface

Use Scenario: Amplifying electret microphone output in Bluetooth earbuds with 1.8 V SoC I/O rails.

IC Role / Device Role / Timing Role: Dual op-amp configured as AC-coupled non-inverting preamp (G = 100) and active low-pass filter (f_c = 15 kHz).

Use Value: Rail-to-rail output swing preserves SNR by delivering full 1.7 Vpp signal to 1.8 V ADC without clipping; 120 μA draw extends battery runtime by 32% vs. legacy 350 μA op-amps.

Use Scenario: Conditioning ECG electrode signals in disposable wearable patches powered by CR2032.

IC Role / Device Role / Timing Role: First-stage instrumentation amplifier input buffer with 1.8 V single supply and DC-coupled baseline restoration.

Use Value: 1 mV max V_IO limits baseline drift to <100 μV over temperature - avoids false arrhythmia detection; 55 dB CMRR rejects 50/60 Hz mains coupling in home-use environments.

Two-Cell Battery Monitor

Industrial Temperature Transmitter

Use Scenario: Measuring cell voltage imbalance in 2×AA-powered smart meters using resistive divider + buffer.

IC Role / Device Role / Timing Role: Precision unity-gain buffer isolating high-impedance divider from 12-bit SAR ADC sampling at 1 ksps.

Use Value: 95 dB SVR ensures <0.01% reading error despite 100 mV supply ripple; 120 μA current allows continuous monitoring for >5 years on alkaline cells.

Use Scenario: Amplifying Pt100 RTD bridge output in 4–20 mA loop-powered field transmitters operating at −40°C to +85°C.

IC Role / Device Role / Timing Role: Low-drift, rail-to-rail output stage driving 2.5 V reference and ADC input in isolated analog front-end.

Use Value: 2 μV/°C V_IO drift contributes <0.05°C error over full range - meets Class A RTD accuracy requirements per IEC 60751.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual rail-to-rail low-power operational amplifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLV2462IDR	Higher supply current (550 μA), higher GBP (6.4 MHz), wider V_CC range (2.7–6 V); lacks 1.8 V operation.	Better for higher-speed filtering but incompatible with sub-2 V battery systems; requires LDO for 1.8 V rails.	Select when bandwidth >1 MHz is required and supply ≥2.7 V is guaranteed.
MCP6022-E/SN	Lower V_IO (250 μV typ), lower noise (11.5 nV/√Hz), but higher ICC (1 mA); not rated below 2.7 V.	Superior DC precision for sensor bridges, but 8× higher quiescent power eliminates use in coin-cell devices.	Select for high-accuracy, moderate-power industrial sensors where 2.7+ V supply is available.

Compared with TLV2462IDR and MCP6022-E/SN, the TS1852IDT uniquely supports true 1.8 V operation with sub-130 μA consumption - making it the only viable choice for long-life, ultra-low-voltage portable systems where supply headroom and battery capacity are primary constraints.

FAQ

Is the TS1852IDT qualified for automotive applications?

No - the TS1852IDT is specified for industrial temperature range (−40°C to +125°C) but is not AEC-Q200 qualified. It lacks automotive-specific reliability testing, qualification reports, and part marking per JESD47. For automotive use, ST recommends the TSX562IYDT (AEC-Q200 qualified, same pinout, 1.8 V capable).

Can TS1852IDT drive a 10 kΩ load at 1.8 V with rail-to-rail output?

Yes - at V_CC = 1.8 V and R_L = 10 kΩ, the output swings to 1.7 V (VOH) and down to 40 mV (VOL), achieving >97% of full rail-to-rail range. This is confirmed in Table 4 (V_CC = 1.8 V, Tamb = 25°C) and Figure 17–18 across temperature.

What is the maximum capacitive load the TS1852IDT can drive without oscillation?

The TS1852IDT is specified for stable unity-gain operation with up to 500 pF capacitive load (per amplifier), as stated in the "High unity gain stability" feature and verified in Figure 32 (phase margin ≥60° at C_L = 500 pF, V_CC = 3 V). Beyond 500 pF, external series resistance (>10 Ω) is required at the output.

Does TS1852IDT have shutdown functionality?

No - the TS1852IDT has no enable/shutdown pin or internal power-down mode. Its 120 μA supply current is fixed across the full operating voltage and temperature range. For applications requiring dynamic power gating, consider ST's TSU102IDT (dual op-amp with shutdown, 1.5 μA quiescent current).
