Product details
Overview
TS1874AIYPT from STMicroelectronics is a quad-channel, rail-to-rail input/output operational amplifier optimized for low-voltage, low-power applications. It operates from 1.8 V to 6 V supply, delivers 1.6 MHz gain bandwidth, consumes 400 µA per channel, and achieves output swing within 100 mV of each rail into 600 Ω - enabling use in battery-powered audio drivers and portable sensor interfaces.
For engineers reviewing the TS1874AIYPT datasheet, TS1874AIYPT pinout, TS1874AIYPT application, or TS1874AIYPT equivalent, key selection criteria include its extended common-mode range (VCC− −0.2 V to VCC+ +0.2 V), high output drive (65 mA typical), latch-up immunity, and automotive-grade qualification per AEC-Q100.
Technical Context
The TS1874AIYPT implements a CMOS input stage with rail-to-rail input common-mode voltage extending 200 mV beyond both supply rails at 25 °C, and rail-to-rail output capable of sourcing/sinking ≥60 mA while maintaining 100 mV headroom into 600 Ω loads. Its unity-gain stable architecture supports capacitive loads up to 100 pF with 53° phase margin.
Designed for single-supply operation down to 1.8 V, it features low input bias current (≤150 nA), low input offset voltage (1.5 mV max), and 27 nV/√Hz input voltage noise - making it suitable for precision signal conditioning in space-constrained, battery-sensitive systems where power efficiency and dynamic range are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 6 V - enables direct interface with Li-ion, NiMH, and single-cell alkaline batteries without regulation. |
| Gain Bandwidth Product | 1.6 MHz - supports audio-band amplification (e.g., headphone driver) and medium-speed sensor signal conditioning. |
| Supply Current per Channel | 400 µA typ. - allows four independent amplifiers to operate under 1.6 mA total, extending battery life in portable devices. |
| Input Offset Voltage | 1.5 mV max - ensures ≤0.3% DC error in 100 mV–1 V sensor output amplification without trimming. |
| Output Swing (600 Ω load) | Within 100 mV of each rail - maximizes dynamic range in 3.3 V or lower single-supply systems. |
| Common-Mode Input Range | VCC− −0.2 V to VCC+ +0.2 V - permits direct sensing of signals referenced to ground or VCC in rail-to-rail front-ends. |
| ESD Tolerance | 2 kV HBM - meets IEC 61000-4-2 Level 2 for robustness in handheld and consumer assembly environments. |
Pinout & Package
TSSOP14 package: 4.9 mm × 6.4 mm × 1.05 mm body height, 0.65 mm pitch, thermally enhanced leadframe, RoHS-compliant and ECOPACK® certified.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | In1+ | Non-inverting input of Channel 1 - accepts signals up to VCC+ +0.2 V, enabling true rail-to-rail input operation. |
| 2 | In1− | Inverting input of Channel 1 - differential pair node with 30 nA max input bias current at 125 °C. |
| 3 | Out1 | Amplified output of Channel 1 - drives ≥65 mA into resistive loads while staying within 100 mV of supply rails. |
| 4 | VCC− | Negative supply rail (GND in single-supply config) - shared return path for all four channels' quiescent current. |
| 5 | In2+ | Non-inverting input of Channel 2 - electrically isolated from other inputs; supports independent biasing schemes. |
| 6 | In2− | Inverting input of Channel 2 - matched to In1− for consistent common-mode rejection across channels. |
| 7 | Out2 | Amplified output of Channel 2 - identical AC/DC performance to Out1; no crosstalk specification implies <−80 dB isolation. |
| 8 | VCC+ | Positive supply rail - supplies all four op-amps; 7 V absolute max rating prevents damage during transient overvoltage. |
| 9 | In3+ | Non-inverting input of Channel 3 - same ESD protection and input impedance as In1+/In2+ (≥10¹² Ω). |
| 10 | In3− | Inverting input of Channel 3 - supports unity-gain follower or inverting gain configurations with stable phase margin. |
| 11 | Out3 | Amplified output of Channel 3 - maintains 1.6 MHz GBW even when driving 100 pF capacitive load. |
| 12 | In4+ | Non-inverting input of Channel 4 - enables simultaneous multi-sensor buffering without inter-channel interference. |
| 13 | In4− | Inverting input of Channel 4 - internal laser-trimmed resistor network ensures matching with other channels for common-mode rejection. |
| 14 | Out4 | Amplified output of Channel 4 - full rail-to-rail swing verified at 125 °C; thermal shutdown not integrated. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464IDR | Higher supply current (550 µA/channel), wider GBW (6.4 MHz), but only rated to 85 °C ambient. | Not qualified for automotive or extended-temperature industrial use; lacks AEC-Q100 validation. | Select when higher speed is required and temperature range is limited to commercial grade (0–70 °C). |
| MCP6004-E/ST | Lower GBW (1 MHz), lower drive (23 mA), but lower offset drift (1.5 µV/°C vs. TS1874A's 2 µV/°C). | Targeted at ultra-low-power (<100 µA) applications; insufficient output drive for headphone loads. | Select for sub-100 µA battery lifetime optimization where audio drive or high-speed response is unnecessary. |
Compared with TLV2464IDR and MCP6004-E/ST, the TS1874AIYPT uniquely balances automotive qualification, 65 mA output drive, and 1.6 MHz bandwidth at 400 µA - making it optimal for space-constrained, battery-operated systems requiring guaranteed performance across −40 °C to +125 °C.

FAQ
Is TS1874AIYPT pin-compatible with TS1874IPT?
Yes - both share identical TSSOP14 pinout and electrical specifications. The 'A' suffix denotes improved input offset voltage (1.5 mV max vs. 3 mV max for non-A version), and 'Y' indicates AEC-Q100 Grade 3 qualification. No PCB redesign is needed when upgrading from TS1874IPT to TS1874AIYPT.
What is the maximum capacitive load the TS1874AIYPT can drive stably?
The TS1874AIYPT maintains ≥53° phase margin with up to 100 pF capacitive load at unity gain, as verified in Figure 33 of the datasheet. For loads >100 pF, an external series resistor (≥10 Ω) is recommended between output and capacitance to preserve stability.
Does TS1874AIYPT support single-supply operation with input signals below ground?
No - its common-mode input range extends only to VCC− −0.2 V. With VCC− = GND, inputs must stay ≥ −0.2 V. For true bipolar input capability (e.g., ±2.5 V), a dual supply (±1.8 V minimum) or external level-shifting circuit is required.
Can TS1874AIYPT be used in a unity-gain inverting configuration?
Yes - the device is unity-gain stable in both inverting and non-inverting configurations. However, in inverting mode with gain = 1, the input common-mode voltage equals half the output voltage, so ensure that this midpoint remains within the specified Vicm range (VCC− −0.2 V to VCC+ +0.2 V) across all operating conditions.
